User ID codes for online verification

ABSTRACT

Methods and systems for establishing a chain of relationships are disclosed. An identity verification platform receives a first request for registration comprising an identification of a first user, identification of an entity, and a relationship between the first user and the entity; verifies the identity of the first user and the relationship between the first user and the entity; and verifies that the entity is legitimate. Once a relationship between a first individual, invited by the first user, and the entity is confirmed, the platform creates a custom badge representing the relationship between the first individual and the entity for display on the entity&#39;s website. The platform receives an identification of a selection by an end user of the custom badge and, responsive to receiving the identification of the selection, renders, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to systems and methods for managing the identity of users and identifying users to third parties using user ID codes in an online verification platform.

BACKGROUND

Banks and financial institutions have long been required to verify the identity of a customer and to verify the authenticity of information provided by that customer when the customer seeks access to a new product or service, for example when opening a new account or applying for a loan. This trend has quickly spilled over into other sectors, particularly considering the rise in e-commerce and our increasingly digital lives. The result of this trend is that digitized personal information is constantly increasing, as are security breaches and data theft.

The ability to store and share information digitally offers many benefits, and the digitization of data has increasingly grown. However, alongside the advantages of cost and convenience, a new set of concerns has developed. The ability to copy and share data has raised questions about the security and privacy of personal data. There have been many high-profile hacks, leaks, and theft of personal information, as well as cases where unencrypted data has simply been lost or left vulnerable to theft. In 2016 alone, 15.4 million adults in the U.S. were victims of identity fraud, an increase of 16% over 2015, and victims suffered losses amounting to $16 billion. Personal identifiable information (PII) was the most common form of data stolen, accounting for almost 43% of data breaches, and the services industry was most affected by data breaches, accounting for almost double the occurrence of the finance, insurance, and real estate sectors combined.

Inefficiencies in the identify verification industry have both financial and social costs. Without proof of identity, an individual may be unable to exercise a range of legal rights, including the ability to vote, access health care, and receive social welfare. Lack of identity documentation and the high costs of obtaining it means that many individuals globally are wholly or partially denied access to banking facilities. In low-income countries, new births often go unregistered because parents struggle to acquire the necessary documentation to have verified and recorded reliably by the relevant authorities. Individuals or companies may misrepresent their identity or their relationship to one another, which can cause investors, consumers, and the general public to be misled into believe a false assertion, which may cause them personal, reputational, and financial harm.

Identify verification processes are often intrusive or time-consuming to individuals, and they come at a significant cost to those required to carry them out as a matter of law and to avoid commercial and reputational losses due to fraud. It may cost a financial institution such as a bank $15 or more to on-board a single customer and verify their identity and personal information. This process gets repeated every time the same consumer tries to access another product or service, despite the process being similar, if not identical, for most organizations. The time it takes to initially validate information has a detrimental impact on customer relations and invariably also impacts customer acquisition and conversion rates for the sales of products where verification of consumer identity or information is required. Consumers are forced to fill in lengthy application forms and provide extensive personal information, and institutions are being forced to collect sensitive data that they arguably don't need to transact with a customer.

The same overhead and inefficiencies are present in other sectors where highly sensitive data may need to be verified, including in background checks for employment. The sharing economy, which relies heavily on trust and on the verification of identity and personal information, grew an average of 32.4% per annum from 2014 to 2016 and now includes 27 million adults in the U.S., demonstrating the growth and scale driving demand for identify verification services beyond the financial sector.

In the online world today, there are many situations where companies or individuals claim a relationship to another person or entity on websites and a third-party user has no way to know the authenticity of that relationship. This may take the form of “Mr. Jones is an advisor to our business”, “Ms. Smith has endorsed our product”, etc. There is significant value to the company to be able to demonstrate the claimed relationship is genuine. There is significant value to the individual with whom the relationship is claimed as it protects their own reputation from misuse. There is significant value to a third party visiting the web site as they may make decisions based upon the claimed relationship, endorsement or recommendation presented to them.

In an effort to combat identity theft, systems and methods for identifying users to third parties have been developed. In a common two factor application, a user presents a bank card or credit card in addition to the personal identification number (“PIN”) corresponding to the card. In other systems, a user provides a password to identify himself/herself and may be given a Short Message Service (SMS) test message or a phone call with a unique code that the user must recite for access. In still other systems, a user may be given challenge questions to verify his/her identity. Each of these systems, however, is subject to attack and ultimate defeat from a basic security breach.

An identity verification system manages trusted digital identities and enables the use of those trusted digital identities to facilitate interactions between people in society. Digital identities include a collection of attributes and their values which can be used to identify the entities of a system and allow those entities to make identity claims. Identity management includes many aspects including creation of an identity, validation of an identity, storage of the identity, maintenance and updates to the identity, and protection of the identity from theft and unauthorized use. Use of identities allow a person or a computer to recognize other entities involved in an interaction and based on that to determine a role, scope of access, scope of authorization, and scope of actions that an entity can perform.

There have been various other ways to perform certifications on online systems. Security certifications have been used to issue badges, only rendering these badges on specific domains. These badges cannot be used for individuals. LinkedIn profile integrations are possible to verify an individual in an online system however these are not secure and are easy to fake.

Prior to discussing specific implementations, it may be helpful to briefly discuss some concepts and systems utilized by the disclosed systems and methods.

Blockchain

Most identity management systems are in large, centralized databases or server repositories that are centrally managed. Such a centralized database or server represents a single point of trust, and a single point of failure. All participants in a system that relies on such a centralized database must place a high level of trust in the correct operation and accuracy of the data stored in the centralized database. Additionally, malicious actors have a centralized point to focus an attack on, and a security breach or leak would have significant scale and impact. Centralized security services typically require users' sensitive and secret data, including secret keys and passwords, to be stored in repositories. Even when hashed or encrypted for security, most people do not have strong passwords, and existing breaches can be used to discover hashed passwords and keys.

Typical identity management systems that centrally store a user's explicit identifying attributes and their sensitive security credentials cannot provide privacy and anonymity of users or of user's data or of user's transactions. There is nothing to stop an identity management system from collecting personal and transaction data and sharing this data in unauthorized ways and without user consent, for example to consumer intelligence and consumer behavior analytics companies.

A blockchain, which is a peer-to-peer network also known as a distributed ledger, offers a compelling solution to the problem of combining accessibility with privacy and security. Records can be held securely and yet openly authenticated, referenced and documented so that data can be trusted as reliable. A blockchain represents an archive of data and transactions that are performed in a data processing system.

A blockchain enables peer-to-peer online transaction of information with overall consensus without the need for a trusted intermediary. This was achieved by contriving a system in which it is difficult (from the standpoint of computational resources) to add transactions to the blockchain, but easy for anyone to check whether transactions are valid. The difficulty means that there is a cost involved in attempting to process transactions, and rewards for doing so legitimately in the form of new currency or transaction fees. Fraudulent transactions are quickly identified and discarded from the blockchain. Attempting to add a fraudulent transaction is costly, entails foregoing the financial incentives for acting honestly, and is highly unlikely to succeed because no single party in the overall network has more than a small proportion of the overall ‘authority’ to validate transactions. In practice, it is simpler and more profitable to act honestly. Because the blockchain is maintained by a large network of participants, no one actor can easily gain enough influence to submit a fraudulent transaction or successfully alter recorded data (although possible in theory with enough resources, it would be prohibitively expensive in practice, particularly for larger blockchain implementations). Any change that a party attempts to make to the blockchain is recognized and rejected by the majority. Everything that takes place on the blockchain is visible to anyone. It is possible to see everything that has ever been recorded on the blockchain.

Blockchain addresses are strings of random characters that cannot intrinsically be associated with a specific individual. While it is easy for the owner to prove they control an address if they wish, and it is often possible to build up a picture of transaction relationships due to the transparent nature of the blockchain, the address itself does not contain the owner's PII. This enables a high degree of privacy when required.

Blockchain is promising for identity management because the data stored in a distributed ledger are all public and therefore not vulnerable to theft. Data integrity is protected and therefore not vulnerable to illegal or accidental modifications, and the data is time-stamped so that its provenance can be validated. Data is sequenced in a cryptographic time chain so illegal insertions of false data is impossible. These ledgers operate without the need for a trusted third-party and without the need to trust any component of the system overall. The blockchain is policed by every member of the network and its integrity checked and agreed by the network on an ongoing basis. Because of this immutability, a transaction that has been accepted into the network cannot be reversed. With no trusted intermediary to act on behalf of the user or control the movement of their funds, blockchain transactions are immune to chargebacks and are like paying in physical cash, but online.

Bitcoin

Bitcoin is a peer-to-peer currency that was launched in January of 2009 as blockchain's first application. Bitcoin's innovation was solving the so-called ‘double-spend’ problem in online financial transfers: the issue that data is readily copied, and that it is therefore impossible to prevent the same funds from being sent to more than one recipient unless there is a trusted intermediary to keep accounts. This centralized model was used by all banks and payment processor who dealt with electronic funds transfers. Such a centralized approach always involves trust, because there must be an authority whose job it is to organize the transfer of money from one account to another. In the physical world, money is handed over directly from one person to another person. Online, however, there must be intermediaries. Rather than transferring funds from their account directly to the recipient, the user instructs the intermediary to move funds on the user's behalf.

This centralized system has a number of potential drawbacks. The trusted intermediary may prove untrustworthy, they have control over the user's funds, and they can ultimately block or reverse transactions. The centralized nature of online banking and other online money transfer protocols leaves users vulnerable to intervention by these trusted intermediaries and comes with security risks, because there is always a single point of failure. Centralized databases can be hacked, and their administrators compromised or coerced by a range of actors.

The bitcoin blockchain was designed for peer-to-peer online transfers of value, effectively acting as digital cash. It achieves this not by moving money from one address to another, but by maintaining and updating the ledger to reflect how much money is registered to each address. The same approach to recording data transparently, securely and immutably by consensus of the entire network can be extended to many other applications (since the financial value in the bitcoin network is simply information about who owns what). For example, messages can be stored on the blockchain, either encrypted or in plain text. Additionally, secondary tokens representing assets, such as shares in a business, securities, commodities, and other currencies, can be secured on the blockchain.

Smart Contract Platforms

It is also possible to create a system that takes a similar approach to the execution of computer code. Software has historically been run on a single computer or centralized server, just as online money transfers have historically been centralized. Smart contracts are code that is executed on the blockchain, called decentralized applications, or ‘dApps’ Once uploaded to the blockchain, these are stored immutably and run when the required conditions are met.

Smart contracts are also known as self-executing contracts, blockchain contracts, or digital contracts, are stored and replicated on a distributed ledger and supervised by the network of computers that run the distributed ledger. In this format, contracts are converted to computer code that can execute a function when invoked. A smart contract between parties is written as code into the blockchain. The parties involved are anonymous, but the contract is in the public ledger. A triggering event takes place and the contract executes itself according to the coded terms. In contrast to the Bitcoin blockchain, which is designed to execute the specific function of transferring value in BTC, a smart contract platform is a general purpose blockchain. Examples of general purpose blockchains which can support smart contract platforms include ETHEREUM, provided by Ethereum Foundation of Zug, Switzerland, ROOTSTOCK (RSK) provided by Rootstock Cloud ERP of San Ramon, CA, EOS provided by EOS of Livonia, MI, NEO provided by NEO of Shanghai, CN, and DFINITY provided by DFINITY of Palo Alto, CA Blockchains requires that transaction fees are paid in the native currency of the blockchain, for example bitcoin (‘BTC’) for the Bitcoin blockchain, and ether (‘ETH’) for the Ethereum blockchain. Fees for executing transactions on the Ethereum blockchain are related to computational complexity, bandwidth, and storage needs (in a system known as “gas”). Gas units each have a price that can be specified in a transaction. Smart contract platforms allow for the creation of separate tokens that are distinct from the native currency. As noted previously, these tokens are digital assets, cryptographically secured upon the blockchain, which can represent whatever the issuer wants and is prepared to back (if necessary), and which can play whatever role in the system that its rule-set determines. These tokens can be transferred on a peer-to-peer basis for a transaction fee, just like native currency (e.g. ETH). They can be incorporated into smart contracts as an integral part of the system. In some implementations, a token or tokens may represent a state or status. In an example, a token is used to represent that a user has satisfied transaction policies required to interact with a transactional protocol. “Transaction policies” may refer to a set of policies which govern a transactional protocol and govern the ecosystem transactions which are executed. “Transactional protocol” may refer to a protocol that operates by receiving, validating, and processing ecosystem transactions. State of the transactional protocol may change as a result of the processing of ecosystem transactions. The transaction policies may also be referred to as transaction rules. Examples of the format of a token may include an entry in a database, an entry on a list, an entry at an address or in an account on a centralized or distributed digital ledger. A token may also be known as a gateway token.

The identify verification industry has grown in response to the changing cultural, societal, and regulatory landscape concerning personal data, and a number of service providers now offer easy API access to multiple sources of consumer data for identify verification purposes. This largely ad hoc approach has resulted in an outdated, costly, and inefficient system. Accordingly, there is a need for a transformative solution that allows individuals and organizations to easily, securely, and cost effectively obtain proof that identity verification information has been authenticated by a trusted institution without organizations sharing any PII between them, leveraging blockchain and smart contracts technology.

Game Theory

In game theory, a non-cooperative game is a game with competition between individual players and in which only self-enforcing alliances are possible due to the absence of external means to enforce cooperative behavior. Non-cooperative game theory focuses on predicting which coalitions will form, the joint actions that groups take and the resulting collective payoffs. A Nash equilibrium is a solution concept of a non-cooperative game involving two or more players in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only their own strategy. If each player has chosen a strategy and no player can benefit by changing strategies while the other players keep theirs unchanged, then the current set of strategy choices and the corresponding payoffs constitute a Nash equilibrium. The Nash equilibrium provides a way of predicting what will happen if two parties are making decisions at the same time, and if the outcome depends of the decisions of each other.

A. Computing and Network Environment for Identity Management Marketplace

In a general overview FIG. 1 is an illustration of an identity validation system 100, including user 102 a, requester 116, validator 100, and attestation blockchain 114.

Referring to FIG. 1 in more detail, any member of the system can be an incentivizing party to introduce new users to the system. For example, in step 120, user 102 a may introduce new user 102 b to the system. Introduction to new users may happen on an incentivization mechanism with tokens that other participants collectively provide to accelerate the overall adoption of the system. Validator 100 may be, an individual, a group of individuals, an entity or service provider that is trusted to validate a user's PII. Examples of validators 100 include but are not limited to financial institutions such as s banks, a government entities, other companies such as utility providers, and verification providers, such as biometrics, network solutions, and device identification providers. User 102 a's PII may include elements such as name, phone number, e-mail address, address (street, city, country, post code), SSN or FEIN or other government identification number, date of birth, advisory board, number of employees, and any other information that is personal or tied to a specific user.

In some embodiments, user's PII may be structured in a hierarchy. In some embodiments, the structure of user 102 a PII may follow a defined model. In some embodiments, the structure of user 102 a PII may follow an industry standard for a container or framework for personal data. In some embodiments, the negotiation of the interchangeable structure of user 102 a PII and the attestation may be dynamic between participants in the system.

In an embodiment, the probability of a portion of the PII in an attestation is achieved by organizing the PII into a Merkle tree, also known as a hash tree. Hash trees allow efficient and secure verification of the contents of large data structures. In some embodiments, a cryptographic hash function such as SHA-2 (National Security Agency, United States) is used for the hashing. The main difference between a hash tree and a hash list is that one branch of the hash tree can be verified independent of the rest of the tree. This is advantageous in an identity verification application since the data structure containing the PII can be split up into smaller data blocks containing a subset of the PII, so that a user 102 a may share only the PII that the requester 116 has asked for, without sharing PII that is not needed or was not requested. In addition, if user 102 a wants to update only a portion of their PII, they can revoke and change only this portion of the PII, while not having to revoke and have re-attested the entirety of the PII that is stored. For example, if user 102 a moves and has a new physical address, but their other PII has stayed the same, validator 100 may be used to authenticate the new physical address and then revoke the node of the existing attestation that contained user 102 a's previous physical address. A new node is then added with the attested new physical address.

In some examples, for example when implemented on the bitcoin blockchain, each node in the hash tree represents an element of the user PII (for example, name) and contains a hash of its content and a hash of the hashes of its child nodes (for example, first name and last name). The resulting ‘root hash’ (also known as the Merkle root) can be used as a fingerprint for the PII being attested to. In step 110, validator 100 writes the attestation on the attestation blockchain 114 in the form of a root hash which is signed by validator 100 using the validator's private key. Validator 100 records an attestation of user 102 a PII by creating a derived address (an ‘attestation address’) where small amounts of cryptocurrency (e.g. “dust”, or a smallest allowed non-zero value) can be spent. The root hash is converted to a valid bitcoin blockchain address using the additive property of elliptic curve cryptography (‘ECC’): k _(priv) +h=k _(attest)

Where k_(priv) is the private key of the validator, h is the root hash, and ‘+’ represents addition in the ECC sense. This blockchain address makes it unfeasible to determine the user 102 a and validator 100 associated with the blockchain address, which is essential to protecting the privacy of the participants. If user 102 a does not wish to reveal all of the underlying PII that was attested to, portions of the hash tree can selectively be revealed, with only hashes provided for any elements user 102 a prefers not to reveal.

Using a smart contract platform, the system would store the signed root hash at a discoverable location. Revocation status may in this case also not be represented by unspent currency, but rather modeled as a parameter of the attestation. A participant in the system may reproduce the hash by creating it from the original PII information or from partial information of the original PII if the user 102 a provides intermediate hashes of the Merkle tree. This allows user 102 a to share PII information with another participant in the system and prove that it is the same data that was previously attested to by validator 100. Should validator 100 or user 102 a wish to revoke an attestation for any reason, this revocation is reflected in an associated blockchain transaction, but the details of the attestation can never otherwise be changed.

In step 106, validator 100 sends the attestation of the user 102 a's PII to user 102 a to store on the user's device. The transmission of the PII from the user 102 a to the validator 104, and the transmission of the attestation of the PII from the validator 100 to user in step 106 may be secured using end to end encryption or transport encryption as is known in the art. In some embodiments, user 102 a stores the PII on their device. The PII may be encrypted locally on the device before it is stored, for example using biometric data or locks such that only the user may be able to access the plain text PII. The attestation of the PII from validator 100 may be stored on the user's device. Metadata or other information about validator 100 may additionally be stored on the user's device. In some embodiments, information such as name, address, identification number (SSN or FEIN for example) and contact details of validator 100 are stored on the user's device 306. In some embodiment, a trust level or reputation of the validator 100 is stored on the user's device 306. The specific attestation that validator 100 issued and metadata to it are also stored on the user's device, ad user sends this information to the requester when the requester presents PII.

These properties of a validator 100 may be validated against the attestation blockchain 114 in order for a third party to determine its authenticity. In some embodiments, the identify verification system operator or a government entity may attest the information that the user 102 a claims about the validator 100. The attestation and its metadata which includes the public key of the validator 100 may also be stored on the user's device 306 as the user 102 a has to provide this information to the requester 116 to be able to validate PII against the attestation blockchain 114.

User 102 a may try to initiate an interaction with requester 116. For example, requester 116 may be a car rental agency and user 102 a may request to rent a car. To proceed with the interaction, in step 118, requester 116 may request PII from user 102 a. Requester may request the user's first and last name, date of birth, credit card number, credit card expiry date, credit card security number, and billing address for the user's credit card. In some examples, requester 116 may request additional information, such an accident history of user 102 a, or insurance claim information for user 102 a. In some embodiments, requester 116 may provide to user 102 a a list of validators that requester 116 trusts.

In some examples, user 102 a has the data that requester 116 requires in attested form, from a validator 100 that requester 116 trusts. In step 108, user 102 a may supply the requested PII in readable form to requester 116, along with information about validator 100 that authenticated the data. In some examples, the information about validator 100 includes the validator's public key. In some examples, information about validator 100 includes information about the hashing algorithm used by validator 100. In some examples, user 102 a uses end to end encryption when sending PII to the requester 116 to make sure that the PII is not visible to other parties if it were to be intercepted. In some examples, user 102 a sends the PII in attestation form created by the validator 100 to requester 116.

In step 112, requester 116 may use the requested PII from user 102 a and the information about validator 100 to check the data authenticity, ownership, and validity of the PII on attestation blockchain 114. In some examples, requester 116 uses the information about validator 100 to create a hash of the plain text PII sent from user 102 a using the same technique, hashing algorithm, and public key that validator 100 used to create the attestation on attestation blockchain 114. In some examples, requester 116 creates the attest key using the hashed user PII and the validator's public key, and this attest key is an address on attestation blockchain 1141 f requester 116 is able to find the transaction for user 102 a at this address on blockchain 114, then requester 116 can be certain that the plain text PII sent to them by user 102 a has been attested to and can be trusted, and requester 116 may proceed with the transaction that user 102 a initiated.

In a general overview, FIG. 2 is an illustration of the token economy system including user 102 a, requester 116, validator 100, attestation blockchain 114, and marketplace blockchain 250.

Describing FIG. 2 in more detail, the token economy system ensures that users remain in control over their PII, as the user must give consent before any identify verification transaction between validator 100 and requester 116 can be completed. In some embodiments, in step 204, user 102 a approaches requester 116 to use a service or purchase a good. Other interactions between user 102 a and requester 116 such as voting, and trading of securities are also supported. In step 208, requester 116 sends user 102 a a list of requirements. In some embodiments, requester 116 sends user 102 a a list of validators 110 acceptable to requester 116, and the user PII that is required. If user 102 a has the required PII attested to by a validator 100 that requester 116 has indicated is acceptable, the requester 116 and validator 110 mutually agree a price for the attested PII. Once the price has been agreed, requester 116 places tokens into an escrow smart contract within the marketplace blockchain 250, then in step 210, user 102 a sends the PII to requester 116 in readable form and sends the attestation and associated metadata (e.g. the validator's public key and other metadata about validator 100) that is required for requester 116 to be able to verify the attestation independently from the plain text PII.

In some embodiments, user 102 a does not have a suitable attestation. In one example, some of user 102 a′a PII that requester 116 has required has been attested to by a trusted validator, but some of the user PII that requester 116 has required has not been attested to by a trusted validator. In some examples, all of the user PII that requester 116 has required has been attested to, but none of the user PII has been attested to by a validator that requester 116 accepts. In some examples, none of the user PII that requester 116 has required has been attested to by any validator. In these and other cases where user 102 a does not have a suitable attestation of the PII that requester 116 has required, user 102 a will be asked to approach a validator that is accepted by requester 116 with the required and unverified PII. In step 212, user 102 a sends unverified PII to validator 100, where validator 100 is a trusted validator for requester 116. Once validator 100 is satisfied with the authenticity of the PII, it will attest to the accuracy and provenance of this information. This attestation, which in some embodiments may be referred to as a fingerprint of the PII, is recorded onto the attestation blockchain 114 in step 218. In step 206, validator 100 sends verified PII attestation and associated metadata to user 102 a for storage on the user's device 306. In some embodiments, the original PII, the attestation, and metadata is stored on the user's mobile device 306 in an encrypted form. Encryption on the mobile device is an independent layer of security that protects against compromise if user's device is lost or stolen. In some embodiments, stored on the user's device are the encrypted raw PII plus the attestation of the PII and the metadata of the attestation, such that the user is able to issues this information to requester 116 if required.

Requester 116 takes user 102 a PII and the information about validator 100 and recreates the hash of the user's PII. Requester 116 is not able to reproduce an attestation, but he is able to reproduce the hash of the PII and verify this against the attestation. In step 220, requester 116 inspects the attestation and the attestation blockchain 114 to see if the attestation is found on the attestation blockchain 114 at the attest address that requester 116 created from the user PII. If requester 116 finds the attestations on the attestation blockchain 114 at the attest address and it has not been revoked, then the PII from user 102 a is verified, and the requester provides the user with the desired service. When this happens, the smart contract running on a marketplace blockchain 250 causes the tokens from requester 116 that are held in escrow to be released. In some embodiments the smart contract running on the marketplace blockchain 250 causes the tokens from requester 116 that are held in escrow to be released to be released to the validator 100 irrespective of whether the requester provides the user with the desired service. In some embodiments, the user 102 a releases the tokens held in escrow as soon as he successfully transmitted the PII, the attestation, and the metadata to the requester. In some embodiments, some tokens are released to the validator 100, the user 102 a, or the system operator. In some embodiments, all of the tokens in escrow may be released to either of validator 100 or user 102 a.

FIG. 3 shows a simplified block diagram of a system 300 for attestations to be shared between identify verification service providers. In a general overview, in some examples, system 300 includes one or more users 102 a. User 102 a may have a device 306. In some examples, system 300 includes one or more service providers 302 and 304. In some examples, system 300 includes an attestation 308 which may be stored on the attestation blockchain 114. In some embodiments, system 300 may utilize a marketplace blockchain 250. One or more smart contracts 310 may be stored on the marketplace blockchain 250. In some embodiments, system 300 may include a token contract 314 and in some embodiments, system 300 may include a pricing contract 312. A token contract may indicate who owns how many tokens. An escrow contract may encode the transaction of tokens between a requester 116 and other system participants, such as a user and a validator. A pricing contract may contain the listing price that a validator asks for a one-time transmission of certain PII between user and requester. In some embodiments, an ontology contract may define what kind of predefined PII are traded in the system. In some examples, an identity verification registry may define what validators are registered in the system as well as a fingerprint of their associated metadata, public key, etc.

Referring to FIG. 3 in more detail, service provider A 302 and service provider B 304 may take on different roles in system 300. The roles that service provide A 302 and service provider B 304 may take on are the same, and in the detailed discussion of these roles, the term service provider will be used generally to refer to any service provider in system 300, including service provider A 302 and service provider B 304. Service provider in system 300 may take on the role of a user in the system. When acting as a requester 116 in the system, service provider may desire to have some information about the service provider attested to by a validator 100 in system 300, for example so that a different service provider in system 300 may be able to verify aspects of the identity of the service provider. When acting as a validator 100 in the system, service provider may be trusted by a user and/or a requester 116 to validate the authenticity and provenance of PII. When acting as a requester 116 in system 300, a service provider may have a requirement to verify PII from a user 120 a in system 300 and may make a request to the user for PII and may make a request to a trusted validator in the system to use an existing attestation of the PII to verify the user 102 a. System 300 may have any number of service providers, and any of the service providers in system 300 make take on any of the roles described. At different times, service provider A may act like a user 102 a, a validator 100, or a requester 116.

In some examples, user 102 a in system 300 may have control over the user's device 306. In some embodiments, user device 306 may be a personal computer or a laptop computer. In some embodiments, user device 306 may be a portable computing device such as a tablet or a smartphone. User device 306 may be a shared device on which user 102 a has a user profile which is accessible to user 102 a by entering a password or pin or other code which is private and known only to user 102 a. In some examples, user device 306 may be a smart watch which may have direct connectivity to a network or may have connectivity to a network through a separate device controlled by user 102 a, such as a smartphone. User device 306 may be a connected car. In general, user device 306 may be any connected device for which all or a partition of the device is solely under control of the user 102 a. In some embodiments, an identity verification application, or any other application, may execute on user device 306, the identify verification application configured to execute instructions that enable functionality of system 300.

Attestation 308 represents a hash of PII of user 102 a that is signed by the validator 100 and recorded on the attestation blockchain 114. Attestation 308 is created by a validator 100 that has checked and verified that authenticity and provenance of the PII, and once assured of its accuracy has created an attestation 308. In some examples, the attestation 308 may include supporting metadata. The supporting metadata may include the verification level of the validator, and the supporting metadata may include details related to the validator's process of verification. In some examples, the supporting metadata may reference any applicable standards that have been used to structure, organize, or encode the user PII in the attestation 308.

In some embodiments, smart contract 310 is used to capture details of an agreement between a validator 100 and a requester 116. In some examples, service provider A 302 is a validator 100 and may have previously attested to the PII that is required from service provider B 304 which is a requester 116, and service provider B 304 trusts service provider A as a trusted validator. In some examples, service provider B 304 acting as requester offers a price to service provider A 302 acting as validator for its attestation of the user's PII. In some examples, the price offered is represented in tokens that are used in system 300. The agreement between service provider B 304 acting as requester and service provider A 302 acting as validator may be captured in smart contract 310. Service provider A 302 acting as validator interacts with smart contract 310 and service provider B 304 acting as requester interacts with smart contract 310. In some examples, smart contract 310 may include details of escrow, where the agreed price in tokens is placed pending the completion of the agreement between user 102 a and service provider B 304 acting as requester. In some examples, smart contract 310 is an application, module, or other software component or code that is stored on the marketplace blockchain 250 and configured to execute when one or more actions take place in system 300. In some examples, smart contract 310 may be an application, service daemon, routine, or other executable logic. Smart contract 310 may be executed on an operating system or on a virtual machine or may be run in any other appropriate environment. In some embodiments, smart contract 310, when executed, causes a graphical user interface to be displayed on user device 306. In other embodiments, smart contract 310 allows for input through a non-graphical user interface, such as a user interface that accepts text or vocal input without displaying an interactive image. A graphical user interface may be displayed on a screen of user device 306, or a monitor connected to a desktop or laptop computer or on any other display. User 102 a may interact with e.g. the graphical user interface on the device by typing, clicking a mouse, tapping, speaking, or any other method of interacting with a user interface. The graphical user interface on the device may be a web-based user interface provided by a web browser (e.g. Google Chrome (Google, Mountain View, California), Microsoft Internet Explorer (Microsoft, Redmond, Washington), or Mozilla Firefox (Mozilla Foundation of Mountain View, California), or may be any other type of interface.

System 300 may include a token contract 314 and a pricing contract 312 as part of the marketplace blockchain 250. A token contract 314 is a distributed ledger on a smart contract platform that tracks the ownership of every token. A pricing contract 312 contains the listing price that a validator 100 requests for a one-time transmission of PII between the user 102 a and requester 116. In some embodiments, other contracts include an escrow contract which encodes the transaction of tokens between the requester 116 and the validator 100 or user 102 a, an ontology contract which defines what kind of predefined PII are traded in the system, and an IDV registry which defines what validators are registered in the system as well as a fingerprint of their associated metadata e.g. public key.

In general overview, FIG. 4A illustrates a method that may be performed by service provider A 302 acting as a validator in system 300. In a general overview of FIG. 4A, in step 400, service provider A 302 verifies user 102 a's PII using its existing verification method. In step 402, service provider A 302 calculates hashes of the user's PII and records a signed attestation to that PII on the attestation blockchain 114. In step 404, service provider A 302 agrees a price for the attestation of the user's PII with service provider B 304. Following transmission of PII between user and requester 116, in step 406 tokens are released from escrow to service provider A.

Referring to FIG. 4A in more detail, in some embodiments, no prior attestation for PII exists. Service provider A 302 verifies the user's PII using its verification methods. Once verified, service provider A 302 calculates the hashes of that PII and records an attestation to that PII on the attestation blockchain 114. In some embodiments, the attestation may also include supporting metadata, such as its verification level, details related to service provider A's 302 process of verification, or any applicable industry standards. In some embodiments, when implemented on a bitcoin blockchain, the blockchain transaction details of this attestation are then provided to the user 102 a from service provider A 302, and the user 102 a stores metadata to the attestation on their device and optionally in a cloud-based or remote storage. Metadata to the attestation may reference the transaction details on the blockchain 114.

In a general overview of FIG. 4B, in step 430, service provider B 304 requests access to all or certain portions of PII from the user 102 a, including the rules/requirements around what data service provider B 304 is willing to accept. FIG. 4B illustrates a method that may be performed by service provider B 304 acting as a requester in system 300. In step 432, service provider B 304 and user 102 a agree on a mutually acceptable validator, service provider A 302, that has previously attested to the data and the rules/requirements around the data. In step 434, service provider B 304 places tokens in escrow according to a smart contract 310 between service provider B 304 and service provider A 302. In step 436, service provider B 304 receives PII from user 102 a in addition to information about service provider A 302. In step 438, service provider B 304 creates a hash of the user PII, validates signature by the validator 100, verifies that the attestation has not been revoked by the validator 100, and compares the hash to a transaction on the marketplace blockchain 250. In step 440, if service provider B 304 is satisfied with the resulting hashes, service provider B 304 provides the good or service to user 102 a.

Referring to FIG. 4B in more detail, in step 430, the identify verification application may determine whether these requirements are met with the PII that was previously attested to by service provider A 302. In step 438, the hash created by service provider B 304 may be compared to a transaction on the marketplace blockchain 250, confirming the authenticity of the requested data. In some embodiments, if service provider B 304 is satisfied with the resulting hashes, service provider B 304 can then purchase the attestation from service provider A 302 and the amount of tokens corresponding to the price of that attestation are released from escrow to service provider A. In some embodiments, the tokens are placed into escrow via the smart contract 310 before the user transmits the PII and service provider B is able to validate. If a validation is not successful, service provider B may be able to refund the tokens back to its account.

In a general overview, FIG. 4C illustrates a method that may be performed by user 102 a in system 300. In step 450, user 102 a requests service provider A 302 to validate user PII. In step 452, user 102 a requests a good or service from service provider B 304. In step 454, user 102 a receives a request for PII and rules or requirements relates to the attestation of the PII from service provider B 304. In step 456, user 102 a agrees with service provider B 304 that service provider A 302 is a mutually acceptable validator that has previously attested to the user's PII according to the rules/requirements related to the PII. In step 458, after the user verifies that an escrow payment exists, the user 102 a sends service provider B 304 the requested PII and information about service provider A 302 which may trigger the release of tokens from escrow. In step 460, user 102 a receives the good or service from service provider B 304.

Referring to FIG. 4C in more detail, a user 102 a may apply for a product or service from service provider A 302 and send the required PII from the identity verification application on the user's device 306. In some embodiments, t\in step 458, the user may send service provider B 304 the requested PII and the necessary information (e.g. required attestation metadata) in order for the requester 116 to reconstruct the Merkle root and compare and validate it against the attestation blockchain 114. In some embodiments, once service provider B 304 has paid the tokens into escrow, the user 102 a, through their identity verification application, can send service provider B 304 the encrypted PII with the necessary information to validate against the blockchain attestation. The requester 116 then reconstructs the Merkle tree hash from the provided attestation and compares it to the attestation on the blockchain. In step 460, the user may receive the goods and services before the tokens are released from escrow. In some embodiments, the tokens may be shared between the user 102 a and service provider A 302 at a ratio defined by the smart contract 310. In some embodiments, requester puts up a certain price in the escrow contract. The system support takes a fee, the validator fee, etc. The user will only hand out the information once they see that the initial payment was escrowed. The user will only release this information once they have verified from their end that the requester has received the data.

In general overview, FIG. 5 shows an illustration of the system goals. In one embodiment, incentives are built into the system through a combination of decisions, flags, penalties and rewards in a repeated interaction between the validator and the requester. The validator is incentivized to maintain their self-defined accuracy or level. This is achieved by requiring that the validator pays a penalty to the network if they are flagged to indicate a belief that they have attested erroneously. No independent party validates that the attestation was actually correct, therefore the penalty is linked to the flagging process of a requires. The validator will pay this penalty out of a stake of tokens. The validator must maintain a minimum stake defined by smart contracts 310 or smart rules of tokens to use the network.

Referring to FIG. 5 in more detail, the requester is rewarded when the validator accepts the statement of the requester. A “correct” flag means, the validator accepts the statement of the requester. No independent party can verify the actual status of the attestation of flag. It's just assumed that the attestation was incorrect when the flag gets accepted, but it not incentivized to falsely report correct attestation. At the Nash equilibrium of the game, whereby no participant in the game can gain an advantage by unilaterally changing their strategy if the other participants maintain their strategies, exists in the system when the validator attest a correct attestation and the requester accepts the correct attestation. In FIG. 5 , R represents the requester, and V represents the validator. ‘+’ represents a reward for behavior in the system, and ‘−’ represents a penalty for behavior in the system. The purpose of the incentives is to achieve equilibrium states, where correct validations that are accepted by requesters lead to rewards to both parties, while incorrectly validated PII correctly rejected yields requester rewards, increasing the overall system reliability.

FIG. 6A shows an extensive form of the interaction between requester 116 and validator 100. To create a decentralized identity management system that exhibits a high level of accuracy, the system makes use of embedded incentives that reward accuracy, and penalties that discourage acting falsely. The accuracy of the system is critical. If the system becomes unreliable or unpredictable, then requesters may avoid using it. The problem is how to decide on whether the information provided by either the requester 116 or the validator 100 is correct or incorrect. In the identity system, there is a second decision to be made by the validator. In the identity system, the user is removed from the design of incentives in the system, because it is assumed that validators treat all user's PII submissions as false, which is why they set out to verify them in the first place. It is the role of the validator alone to ensure the accuracy of their attestations of User PII. This reduces the system to a two-player game comprising a validator and a requester. In this system, the validator provides the requester with an attestation, where the attestation is either correct or incorrect. The requester reviews the attestation and has two options—either to accept or reject it. The requester must be adequately incentivized to reject an incorrect attestation and to accept a correct attestation. In both cases, the outcome is (R (reward); Pe (penalty)). There is no information available regarding whether the validator has provided an incorrect or correct attestation, other than if the requester rejects it. This has the effect that R can never be greater than the utility of a correct attestation (‘CA’). The requester should never be rewarded for rejecting an incorrect attestation (i.e. R<CA).

In general overview, FIG. 6B shows an extensive form of the interaction between requester 116 and validator 100 operating in an outcome space. The requester 116 reviews the validator's 100 attestation and has two options, to either flag the attestation as incorrect or to accept the attestation. If the validator 100 provides an incorrect attestation 604, and the requester 116 accepts this attestation 608, the outcome for both the validator and requester is an incorrect attestation 612. If the validator 100 provides a correct attestation 602 and the requester 116 accepts the attestation 608, the outcome for both the requester and validator is a correct attestation 614. If the requester 116 flags the attestation as incorrect 620, then the validator 100 can either accept 626 or reject the flag 622. The ‘correct flag’ (CF) is the actual reward for a correct flag and the ‘incorrect flag’ (IF) is the actual reward for an incorrect flag. If the validator 100 provides an incorrect attestation 604 and the requester 116 flags this attestation 620, the validator 100 accepts this flag 626. The outcome for the requester 116 and validator 100 are a ‘correct flag’ (CF) and a penalty respectively 628. If the validator 100 provides a correct attestation 602 and the requester 116 flags the attestation 620, the validator 100 rejects the flag 622. The outcome for the requester 116 and validator 100 are an ‘incorrect flag’ (IF) and a penalty respectively 628.

Referring to FIG. 6B in more detail, the penalty is kept the same regardless of whether a validator 100 accepts or rejects a flag. Assuming the primary non-financial motivation of the validator 100 would be to make its own system more robust, this would incentivize honesty through accepting a flag if it is indeed an incorrect attestation, since it costs the validator 100 the same regardless. The validator 100 may only accept correct flags and only reject incorrect flags. Since the penalty is the same regardless of whether the validator 100 accepts or rejects a flag, the validator 100 could potentially reject correct flags to discourage requesters 116.

The four game outcomes can be reduced into a simplified normal form. An attestation game is a sequential game with two actors, a requester and a validator operating in an outcome space {Correct Attestation; Correct Attestation (CA;CA) 614, Incorrect Attestation; Incorrect Attestation (IA; IA) 612, Correct Flag; Penalty (CF; Pe) 628, Incorrect Flag; Penalty (IF; Pe) 624}. A Fee is given by the requester to the validator for the game to be initiated and CF is the actual reward for a correct flag and IF is the actual reward for an incorrect flag.

The following constraints (Proposition 1) produce an exclusive Nash equilibrium of (CA; CA): CA>IF>IA|CA,IF,IA∈

CF>IA|CF,IA∈

-   -   1. (CA; CA): The requester and validator would remain here.         Because CA>IF and CA>IA, this scenario produces more utility for         both. Therefore (CA; CA) is a Nash equilibrium.     -   2. (IF; Pe): The requester would want to move to (CA; CA) to         maximize utility given the validator's action and the validator         is indifferent given the requester's action. Therefore, this is         not a Nash equilibrium.     -   3. (IA; IA): The requester would want to move to (CA; CA) since         CA>IA and so would the validator. Therefore, this is not a Nash         equilibrium.     -   4. (CF; Pe): The requester would want to remain since CF>IA and         the validator is indifferent, it cannot be guaranteed he would         not want to move to (IF; Pe). Therefore, this is not a Nash         equilibrium.         This demonstrates that (CA; CA) is the only Nash equilibrium.

If CF, IF<IA, there is no incentive for the requester to flag the attestation. In a repeated game, if the expected reward from flagging is larger than CA then the requester should flag all attestations. With the addition of additional qualitative constraints:

-   -   1. CF, IF≤|Pe|, since the reward is paid out from the penalty         Pe.     -   2. IA>Pe, since this is additional discouragement for the         validator to provide an incorrect attestation, as the cost of a         penalty is greater than the cost of the incorrect attestation         being accepted.     -   3. Fee<|Pe| to ensure that the penalty a validator faces is         always larger than the Fee it charges, disincentivizing it from         providing incorrect attestations while still making a profit.         We assume IA<0 since the legal consequences of accepting invalid         user data (reputationally and/or financially due to a fine)         would outweigh any short-term convenience

An attestation game is well-posed if the constraints in Proposition 1 and the qualitative constraints are both satisfied. In other words: CA>IF>0>IA>Pe CF>IA and CF,IF,Fee≤|Pe| Given always rational actors in a well-posed attestation game and P (IA) the probability of a validator providing a correct attestation, P (CA)=1−P (IA) the probability of a validator providing an incorrect attestation. Then P (CF):=P ((CF; Pe))=P (IA) and P (IF):=P ((IF; Pe))=P (CA).

Assuming that the validator provides an incorrect attestation, then the requester's choices are to accept it, for a utility gain of IA or to flag it for a utility gain of CF. Since CF>IA and the requester is always rational, the requester will always choose to flag. Therefore P (CF IA)=1, so P (CF)=P (CF IA) P (IA)=P (IA). A similar argument holds for P (IF)=P (CA).

The Reward function Re is a discrete random variable over {(CF; Pe); (IF; Pe)}. With Re ((CF; Pe))=CF and Re ((IF; Pe))=IF. Its probability mass function is given by P(CF)=P(IA) if Re=CF P(IF)=P(CA) if Re=IF Define R as the expected value of Re, that is R:=E[Re]=P(CF)CF+P(IF)IF

A reward function Re (with E [Re]=R) is well-posed if: IA<R<CA and R<|Pe| IF and CF are chosen in such a way that Re is well-posed. The required network incentives are created through a proof-of-stake mechanism making use of the token.

P is the probability of a correct attestation (P(CA)) and

${Level}{= \frac{1}{1 - P}}$ This P is determined by the validator and can also be considered as the validator's accuracy.

In some embodiments, different confidence levels of accuracy are required for different applications. For example, confidence levels greater than 99.9% may be required for critical use cases. Lower confidence levels may be acceptable for less critical use cases. In some examples, it is more costly for a validator to authenticate user PII to a higher confidence level. The system many include many validators that are able to provide different levels of accuracy, with associated adjustments in prices per attestation. In some embodiments, the system includes penalties for validators that create attestations that are not truthful, creating strong incentives for validators to be accurate and truthful.

In general overview, FIG. 7 illustrates sample levels of different validators. Requesters must be confident that validators will maintain a level of accuracy required for their use cases. The identity system of this disclosure is a decentralized system, and the enforcement of accuracy cannot be achieved through a central authority and must instead rely on rewards and penalties. The incentives required to drive the system towards accuracy are created using a branch of game theory called backward induction. In backward induction, the end goal is decided and then a game is designed to attempt to reach this goal.

Rewards and Penalties

In general overview, FIG. 8 illustrates the penalty for a flag as the level varies for different values of a system constant (a).

It is proposed that a penalty Pe satisfies the conditions for a well-posed attestation game and subsequently the rewards for a correct flag (CF) and incorrect flag (IF) which produce a well-posed reward function Re.

${{Pe} = {- \frac{Fee}{1 - {aP}}}},{a \in \left\lbrack {0,1} \right\rbrack}$ a is a configurable parameter that can be adjusted if observations indicate penalties are too high or too low. Fee<|Pe|, in other words the above Pe is valid for a well-posed attestation game. It is noted that

$\left. {0 \leq {aP} \leq 1}\Rightarrow{0 \leq {1 - {aP}} \leq 1}\Rightarrow\frac{1}{1 - {aP}} \right..$ So

${❘{Pe}❘} = {\frac{Fee}{1 - {aP}} \geq {Fee}}$ In the rewards CF and IF the process introduces a weighting factor to include a dependence on the flagging history of the requester. Should a requester have a high ratio of previously accepted flags, it should produce a higher reward. This incentivizes the requester to only submit flags if they are likely to be accepted (i.e. incorrect attestations).

AF is defined as the ratio of accepted flags to the total flags in its history. Clearly 0≤AF≤1. w is defined as w∈[0,1] as the weight parameter to indicate how much AF should be weighed in the rewards. w is configurable based upon the behavior of the system.

The reward for setting a correct flag CF is defined as

${CF} = {\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack \cdot \frac{❘{Pe}❘}{2}}$ and the reward for an incorrect flag IF is

${IF} = {\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack \cdot \frac{❘{Fee}❘}{2}}$

By definition CF, IF<|Pe| and therefore are valid for a well-posed attestation game. For future purposes express CA=Fee+S where S>0 is any savings gained by using the system. We can see 0<IF<Fee<CA as required. Now Re can be defined and the formula for R=E (Re):

$R = {{\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack \cdot {P({IA})} \cdot \frac{❘{Pe}❘}{2}} + {\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack \cdot {P({CA})} \cdot \frac{❘{Fee}❘}{2}}}$ This formula can be simplified to

$R = {{\frac{1}{2}\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack} \cdot \left\lbrack {{{P({IA})} \cdot \frac{Fee}{1 - {aP}}} + {{P({CA})} \cdot {Fee}}} \right.}$

R, as defined, can be shown to be well posed: →0≤P(CA),P(IA)≤1 as they are probabilities, and also

${P\left( {CA} \right)} = {\left. {1 - {P({IA})}}\rightarrow{{w + {\left( {1 - w} \right)AF}} \leq {w + {\left( {1 - w} \right){since}0}} \leq {AF} \leq 1}\rightarrow{{w + {\left( {1 - w} \right)AF}} \leq {w + \left( {1 - w} \right)}} \right. = {\left. {{1{since}0} \leq {AF} \leq {1{by}{definition}}}\rightarrow{{aP} \leq 1}\rightarrow{{1 - P} \leq {1 - {aP}}}\rightarrow{\frac{1}{1 - {aP}} \leq \frac{1}{1 - P}}\rightarrow\frac{1}{1 - P} \right. = \frac{1}{P({IA})}}}$ For R to be well posed it needs to satisfy the constraints previously stated:

${{IA} < R < {{CA}{and}R} < {❘{Pe}❘}}{R = {{{{\frac{1}{2}\left\lbrack {w + {\left( {1 - w} \right){AF}}} \right\rbrack} \cdot \left\lbrack {{{P({IA})}\frac{Fee}{1 - {aP}}} + {{P({CA})} \cdot {Fee}}} \right\rbrack} \leq {\frac{1}{2}\left\lbrack {{{P({IA})}\frac{Fee}{1 - {aP}}} + {{P({CA})} \cdot {Fee}}} \right\rbrack} \leq {\frac{1}{2}\left\lbrack {{Fee} + {{P({CA})} \cdot {Fee}}} \right\rbrack} \leq {\frac{1}{2}{2 \cdot {Fee}}}} = {{{Fee}\  < {{Fee} + S}} = {CA}}}}$ Thus, the constraint R<CA is satisfied. Additionally, since IA<0, then:

$R = {{{\frac{1}{2}\left\lbrack {w + {\left( {1 - w} \right) \cdot {AF}}} \right\rbrack} \times \left\lbrack {{{P({IA})}\ \frac{Fee}{1 - {aP}}} + {{P({CA})} \cdot {Fee}}} \right\rbrack} \geq 0 \geq {IA}}$ The final requirement is that R<|Pe|:

${R \leq \left\lbrack {{{P({IA})}\ \frac{Fee}{1 - {aP}}} + {{P({CA})} \cdot {Fee}}} \right\rbrack \leq \left\lbrack \text{⁠}{{{P({IA})}\frac{Fee}{1 - {aP}}} + {{P\left( {CA} \right)}\frac{Fee}{1 - {aP}}}} \right\rbrack \leq \text{ }{\left\lbrack {{P({IA})} + {P\left( {CA} \right)}} \right\rbrack\frac{Fee}{1 - {aP}}}} = {\frac{Fee}{1 - {Ap}} = {❘{Pe}❘}}$

The parameter a adjusts the penalty and FIG. 8 illustrates how it influences this.

The reward scales with how many previous flags have been accepted. Therefore the requester is also incentivized to be honest when flagging in a repeated game scenario. Even when a requester has had all its previous flags rejected, it is still incentivized to flag an incorrect attestation as there is a non-zero minimum reward (dictated by the weight parameter w). This is a feedback mechanism i.e. if a requester has a high ratio of accepted flags (due to having a high rate of previously accepted flags), and decides (for whatever reason, even though it will always be lower than CA as shown above) to flag correct attestations, it will be rejected, and future rewards will be lower.

Since |Pe|>R in all scenarios, there will be excess incentive amounts |Pe|−R. It is currently proposed that these incentive amounts are locked away separately (not using a centralized solution). In the instance a validator accepts a flag, these incentive amounts will be used to pay out all previous requesters who accepted that attestation or will be distributed to all validators.

In a repeated game, which this is, it can then be shown that regardless of the discount factor (the discount of future game utility), the correct behavior is incentivized.

With a well-posed R in a repeated game with discount factor β<1, accepting correct attestations (honest) is more profitable than always flagging (dishonest). Proof:

The infinite geometric series identity holds as β<1 for convergence:

${{{Honest}{total}{payout}:{\sum\limits_{k = 0}^{\infty}{\left( {CA} \right)(\beta)^{k}}}} = \frac{CA}{1 - \beta}}{{{Dishonest}{total}{payout}:{\sum\limits_{k = 0}^{\infty}{\left( {CA} \right)(\beta)^{k}}}} = \frac{R}{1 - \beta}}$

Staking Mechanism

In general overview, FIG. 9 illustrates the minimum required stake as more IDs are validated for a particular set of values. Specifically, the required stake of a validator with a penalty of 100 tokens per flag who performs 10,000 attestations.

Referring to FIG. 9 in more detail, in order to ensure the right incentives are maintained, a staking mechanism is required. The staking mechanism requires a validator 100 to hold a defined minimum amount of tokens in order to be an active participant in the system. To ensure that validators have a stake and can pay, they must maintain a minimum stake that secures them against expected claims. This ensures that CA:CA is the Nash equilibrium in the repeated game.

The expected claims are:

${EC} = \frac{Total_{ID}}{Level_{average}}$ Where Total_(ID) is the number of IDs that the validator has provided to requesters and Level_(average) is the average level of a validator's IDs.

A stake function Stake_(min): R→R is feasible if:

-   -   1. Stake_(min) (0)≥b·|Pe|, to cover a base amount of flagged         attestations b (configurable by the network and related to EC         when it is a new validator).     -   2.

$\begin{matrix} {{{\lim\limits_{x\rightarrow\infty}{stak{e_{\min}(x)}}} = {{{❘{Pe}❘} \cdot {Claim}_{\max}} + {0(b)}}},} &  \end{matrix}$

-   -    where Claim_(max)         R represents the maximum amount of claims expected for a         validator to reach.     -   3.

$\frac{{dStak}e_{\min}}{dx} > {0{and}\frac{d^{2}{Stak}e_{\min}}{dx}} < {0{for}x\left( {0,\ \infty} \right)}$

-   -   -   In other words, the minimum stake grows with diminishing             additional costs to the validator. The current stake of a             validator must always be greater than or equal to             Stake_(min)(total_(ID)). C

The minimum stake (Stake_(min)(total_(ID))) should be:

${Stake_{\min}} = {{❘{Pe}❘}\left( {b + \frac{Clai{m_{\max} \cdot {Total}_{ID}}}{{growth} + {Total}_{ID}}} \right)}$ Where growth

(1, ∞) modulates how quickly the required stake grows as a function of the total number of attestations of the validator. Proof; Stake_(min)(0)=|Pe|·b trivially as required Let x=Total_(ID). Then:

${{\lim\limits_{x\rightarrow\infty}{{❘{Pe}❘} \cdot b \cdot {❘{Pe}❘} \cdot \frac{Claim_{\max}}{\frac{growth}{x} + 1}}} = {{{{❘{Pe}❘} \cdot b} + {{❘{Pe}❘} \cdot {Claim}_{\max}}} = {{{❘{Pe}❘} \cdot {Claim}_{\max}} + {0(b)}}}}{{\frac{d}{dx}\frac{x}{1 + x}} = {{\frac{1}{\left( {1 + x} \right)^{2}}{which}{is}{positive}{everywhere}{for}x} \neq 1}}{{{\frac{d^{2}}{dx^{2}}\frac{x}{1 + x}} = {{\frac{2x}{\left( {1 + x} \right)^{3}} - \frac{2}{\left( {1 + x} \right)^{2}}} = {{- \frac{2x}{\left( {1 + x} \right)^{3}}}{which}{is}{negative}{\forall{x > {0{since}a^{3}} > 0}}}}},\ {\forall{a > 0}}}$

The stake, through including Pe as a variable, is linearly dependent on fee. This ensures that the stake (and the penalty itself) adjusts to changes in the value of the toke in the system since inflation or deflation of a token may be accompanied by a fee adjustment by a validator. This stake ensures that there is sufficient protection for requesters. If the validator decides to leave the system, the stake decays over time using an exponential function, where more tokens are available to be withdrawn over time in an exponential manner.

The withdrawal stake percentage is defined as 100e^(t-F), where t is the time in minutes since the withdrawal was requested, up to 5 years and F is five years in minutes. At 5 years, 100% of the stake will be withdrawn. After say one year, only 1.83% can be extracted by the validator. Both requesters and validators can also choose to use other parties e.g. requesters can decide which validator to use and validators can decide which requesters to accept.

B. Computing and Network Environment of the Current Disclosure

Prior to discussing specific embodiments of the present solution, it may be helpful to describe aspects of the operating environment as well as associated system components (e.g. hardware elements) in connection with the methods and systems described herein.

In some embodiments, a user client 1002 has the capacity to function as both a client node seeking verify the identity of a third-party using ID codes. In some embodiments, the user client 1002 has a validated identity profile that can be verified by a third-party using ID codes. In examples, a validator client 1007 may be operable to validate the identity of one or more users 1002. In embodiments, a validator client 1007 may be operable to validate an organization, a user, a company, a site, an object, a person, a group of people, and/or the relationship between any of a user, an organization, a company, a site, an object, a person, and a group of people and any other user, organization, company, site, object, person, and group of people. In some embodiments, a verifier client 1003 may wish to verify the identity of a user, a company, a site, an object, a person, a group of people, and/or the relationship between any of a user, an organization, a company, a site, an object, a person, and a group of people and any other user, organization, company, site, object, person, and group of people, through the use of ID codes.

Although FIG. 10A shows a network 1004 between user clients 1002, verifier clients 1003, third-party cosigner clients 1005, attestor clients 1001, validator clients 1007, digital wallet provider clients 1009, and centralized or distributed ledgers 1006, the user clients 1002, verifier clients 1003, third-party cosigner clients 1005, attestor clients 1001, validator clients 1007, digital wallet provider clients 1009, and centralized or distributed ledgers 1006 may be on the same network 1004. In some embodiments, there are multiple networks 1004 between the user clients 1002, verifier clients 1003, third-party cosigner clients 1005, attestor clients 1001, validator clients 1007, digital wallet provider clients 1009, and centralized or distributed ledgers 1006. In one of these embodiments, a network 1004′ (not shown) may be a private network and a network 1004 may be a public network. In another of these embodiments, a network 1004 may be a private network and a network 1004′ may be a public network. In still another of these embodiments, networks 1004 and 1004′ may both be private networks.

The network 1004 may be connected via wired or wireless links. Wired links may include Digital Subscriber Line (DSL), coaxial cable lines, or optical fiber lines. Wireless links may include Bluetooth®, Bluetooth Low Energy (BLE), ANT/ANT+, ZigBee, Z-Wave, Thread, Wi-Fi®, Worldwide Interoperability for Microwave Access (WiMAX®), mobile WiMAX®, WiMAX®-Advanced, NFC, SigFox, LoRa, Random Phase Multiple Access (RPMA), Weightless-N/P/W, an infrared channel or a satellite band. The wireless links may also include any cellular network standards to communicate among mobile devices, including standards that qualify as 1G, 2G, 3G, 4G, or 5G. The network standards may qualify as one or more generations of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by the International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommuniations-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunication Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, CDMA2000, CDMA-1×RTT, CDMA-EVDO, LTE, LTE-Advanced, LTE-M1, and Narrowband IoT (NB-IoT). Wireless standards may use various channel access methods, e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards.

The network 1004 may be any type and/or form of network. The geographical scope of the network may vary widely and the network 1004 can be a body area network (BAN), a personal area network (PAN), a local-area network (LAN), e.g. Intranet, a metropolitan area network (MAN), a wide area network (WAN), or the Internet. The topology of the network 1004 may be of any form and may include, e.g., any of the following: point-to-point, bus, star, ring, mesh, or tree. The network 1004 may be an overlay network which is virtual and sits on top of one or more layers of other networks 1004′. The network 1004 may be of any such network topology as known to those ordinarily skilled in the art capable of supporting the operations described herein. The network 1004 may utilize different techniques and layers or stacks of protocols, including, e.g., the Ethernet protocol, the internet protocol suite (TCP/IP), the ATM (Asynchronous Transfer Mode) technique, the SONET (Synchronous Optical Networking) protocol, or the SDH (Synchronous Digital Hierarchy) protocol. The TCP/IP internet protocol suite may include application layer, transport layer, internet layer (including, e.g., IPv4 and IPv6), or the link layer. The network 1004 may be a type of broadcast network, a telecommunications network, a data communication network, or a computer network.

In some embodiments, the system may include multiple, logically-grouped servers providing the centralized or distributed ledgers 1006. In one of these embodiments, the logical group of servers may be referred to as a server farm or a machine farm. In another of these embodiments, the servers providing the centralized or distributed ledgers 1006 may be geographically dispersed. In other embodiments, a machine farm may be administered as a single entity. In still other embodiments, the machine farm includes a plurality of machine farms. The servers providing the centralized or distributed ledgers 1006 within each machine farm can be heterogeneous—one or more of the servers or machines can operate according to one type of operating system platform (e.g., Windows, manufactured by Microsoft Corp. of Redmond, Washington), while one or more of the other servers can operate according to another type of operating system platform (e.g., Unix, Linux, or Mac OSX).

In one embodiment, servers providing the centralized or distributed ledgers 1006 in the machine farm may be stored in high-density rack systems, along with associated storage systems, and located in an enterprise data center. In this embodiment, consolidating the servers providing the centralized or distributed ledgers 1006 in this way may improve system manageability, data security, the physical security of the system, and system performance by locating servers and high-performance storage systems on localized high-performance networks. Centralizing the servers and storage systems and coupling them with advanced system management tools allows more efficient use of server resources.

The servers 1006 of each machine farm providing the centralized or distributed ledgers 1006 do not need to be physically proximate to another server in the same machine farm. Thus, the group of servers logically grouped as a machine farm may be interconnected using a wide-area network (WAN) connection or a metropolitan-area network (MAN) connection. For example, a machine farm may include servers physically located in different continents or different regions of a continent, country, state, city, campus, or room. Data transmission speeds between servers in the machine farm can be increased if the servers are connected using a local-area network (LAN) connection or some form of direct connection. Additionally, a heterogeneous machine farm may include one or more servers operating according to a type of operating system, while one or more other servers execute one or more types of hypervisors rather than operating systems. In these embodiments, hypervisors may be used to emulate virtual hardware, partition physical hardware, virtualize physical hardware, and execute virtual machines that provide access to computing environments, allowing multiple operating systems to run concurrently on a host computer. Native hypervisors may run directly on the host computer. Hypervisors may include VMware ESX/ESXi, manufactured by VMWare, Inc., of Palo Alta, California; the Xen hypervisor, an open source product whose development is overseen by Citrix Systems, Inc. of Fort Lauderdale, Florida; the HYPER-V hypervisors provided by Microsoft, or others. Hosted hypervisors may run within an operating system on a second software level. Examples of hosted hypervisors may include VMWare Workstation and VirtualBox, manufactured by Oracle Corporation of Redwood City, California

Management of the machine farm may be de-centralized. For example, one or more servers may comprise components, subsystems and modules to support one or more management services for the machine farm providing the centralized or distributed ledgers 1006. In one of these embodiments, one or more servers provide functionality for management of dynamic data, including techniques for handling failover, data replication, and increasing the robustness of the machine farm. Each server may communicate with a persistent store and, in some embodiments, with a dynamic store.

Server providing the centralized or distributed ledgers 1006 may be a file server, application server, web server, proxy server, appliance, network appliance, gateway, gateway server, virtualization server, deployment server, SSL VPN server, or firewall. In one embodiment, a plurality of servers may be in the path between any two communicating servers.

Referring to FIG. 10B, a cloud computing environment is depicted. A cloud computing environment may provide user client 1002, verifier client 1003, digital wallet provider client 1009, third-party cosigner client 1005, and validator client 1007 with one or more resources provided by a network environment. The cloud computing environment may include one or more user clients 1002 a-1002 n, one or more verifier clients 1003 a-1003 n, one or more digital wallet provider clients 1009 a-1009 n, one or more third-party cosigner clients 1005 a-1005 n, and one or more validator clients 1007 a-1007 n in communication with the cloud 1008 over one or more networks 1004. User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may include, e.g., thick clients, thin clients, and zero clients. A thick client may provide at least some functionality even when disconnected from the cloud 1008 or servers providing the centralized or distributed ledgers 1006. A thin client or zero client may depend on the connection to the cloud 1008 or servers providing the centralized or distributed ledgers 1006 to provide functionality. A zero client may depend on the cloud 1008 or other networks 1004 or servers providing the centralized or distributed ledgers 1006 to retrieve operating system data for the user client device 1002, verifier client device 1003, digital wallet provider client device 1009, third-party cosigner client device 1005, and validator client device 1007. The cloud 1008 may include back end platforms, e.g., servers, storage, server farms or data centers.

The cloud 1008 may be public, private, or hybrid. Public clouds may include public servers that are maintained by third parties to the user client 1002, verifier client 1003, digital wallet provider client 1009, third-party cosigner client 1005, and validator client 1007, or the owners of the user client 1002, verifier client 1003, digital wallet provider client 1009, third-party cosigner client 1005, and validator client 1007. The servers may be located off-site in remote geographical locations as disclosed above or otherwise. Public clouds may be connected to servers over a public network. Private clouds may include private servers that are physically maintained by a user client 1002, verifier client 1003, digital wallet provider client 1009, third-party cosigner client 1005, and validator client 1007, or owners of a user client 1002, verifier client 1003, digital wallet provider client 1009, third-party cosigner client 1005, and validator client 1007. Private clouds may be connected to the servers over a private network 1004. Hybrid clouds may include both the private and public networks 1004 and servers.

The cloud 1008 may also include a cloud-based delivery, e.g. Software as a Service (SaaS) 1010, Platform as a Service (PaaS) 1012, and Infrastructure as a Service (IaaS) 1014. IaaS may refer to a user renting the user of infrastructure resources that are needed during a specified time period. IaaS provides may offer storage, networking, servers or virtualization resources from large pools, allowing the users to quickly scale up by accessing more resources as needed. Examples of IaaS include Amazon Web Services (AWS) provided by Amazon, Inc. of Seattle, Washington, Rackspace Cloud provided by Rackspace Inc. of San Antonio, Texas, Google Compute Engine provided by Google Inc. of Mountain View, California, or RightScale provided by RightScale, Inc. of Santa Barbara, California PaaS providers may offer functionality provided by IaaS, including, e.g., storage, networking, servers or virtualization, as well as additional resources, e.g., the operating system, middleware, or runtime resources. Examples of PaaS include Windows Azure provided by Microsoft Corporation of Redmond, Washington, Google App Engine provided by Google Inc., and Heroku provided by Heroku, Inc. of San Francisco California SaaS providers may offer the resources that PaaS provides, including storage, networking, servers, virtualization, operating system, middleware, or runtime resources. In some embodiments, SaaS providers may offer additional resources including, e.g., data and application resources. Examples of SaaS include Google Apps provided by Google Inc., Salesforce provided by Salesforce.com Inc. of San Francisco, California, or Office365 provided by Microsoft Corporation. Examples of SaaS may also include storage providers, e.g. Dropbox provided by Dropbox Inc. of San Francisco, California, Microsoft OneDrive provided by Microsoft Corporation, Google Drive provided by Google Inc., or Apple iCloud provided by Apple Inc. of Cupertino, California

User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may access IaaS resources with one or more IaaS standards, including, e.g., Amazon Elastic Compute Cloud (EC2), Open Cloud Computing Interface (OCCI), Cloud Infrastructure Management Interface (CIMI), or OpenStack standards. Some IaaS standards may allow clients access to resources over HTTP and may use Representational State Transfer (REST) protocol or Simple Object Access Protocol (SOAP). User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may access PaaS resources with different PaaS interfaces. Some PaaS interfaces use HTTP packages, standard Java APIs, JavaMail API, Java Data Objects (JDO), Java Persistence API (JPA), Python APIs, web integration APIs for different programming languages including, e.g., Rack for Ruby, WSGI for Python, or PSGI for Perl, or other APIs that may be built on REST, HTTP, XML, or other protocols. User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may access SaaS resources through the use of web-based user interfaces, provided by a web browser (e.g. Google Chrome, Microsoft Internet Explorer, or Mozilla Firefox provided by Mozilla Foundation of Mountain View, California). User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may also access SaaS resources through smartphone or tablet applications, including e.g., Salesforce Sales Cloud, or Google Drive App. User clients 1002, verifier clients 1003, digital wallet provider clients 1009, third-party cosigner clients 1005, and validator clients 1007 may also access SaaS resources through the client operating system, including e.g. Windows file system for Dropbox.

Potential cosigners can include, but are not limited to, digital wallet provider client 1009, attestor 1001, user client 1002, and third-party cosigner client 1005. Multi-signature records at an attestation address may be revoked if M-of-N cosigners sign a transaction “spending” the record from the attestation address. In implementations, a multisig attestation address comprises two or more public keys and is created using the Pay To Script Hash (P2SH) protocol.

In some embodiments, digital identity platform 2000 includes verifier 1003. Verifier 1003 may be any individual, business, advisor, connection, associate, company, organization, or any other entity that wishes to verify a relationship between connection 2025 and company/organization 2020.

In a general overview, FIG. 12 depicts a method in an identity verification platform used to generate user ID codes for online verification. In some embodiments, the system receives a request for registration of an entity from a company representative, who is a user of the system (step 1210). In embodiments, the system verifies the identity of the user and the relationship between the user and the identity (step 1220). In examples, the system may verify that the entity is legitimate (step 1230). The system may receive from the use an invitation for a relationship between the entity and an individual (step 1240). In embodiments, the system may transmit to the individual a request for approval of the relationship between the entity and the individual (step 1250). The system may receive approval of the relationship from the individual (step 1260). In some embodiments, the system transmits confirmation of the relationship to the user (step 1270). The system may create a custom badge representing the relationship between the individual and the entity in step 1280.

Referring to FIG. 12 in more detail, in step 1210, a company representative (also known as user 1002) sends a request to identity verification platform 2000 to register the company/organization 2020 (also known as the entity). In examples, user 1002 must first sign on to an identity verification system to send the request to register company/organization 2020. User 1002 may be presented with a user interface, such as the user interface shown in FIG. 16 , in order to sign in to the identity verification platform 2000. In some embodiments, user 1002 is not registered with the identity verification system, and to proceed to use identity verification platform 2000, user 1002 must interact with the user interface in order to register with the identify verification system. In some embodiments, user 1002 may be presented with a QR code, for example a QR code similar to that shown in FIG. 17 , which user 1002 can scan with their phone in order to be directed to a website to register with the identity verification system, or in order to be prompted to install an application e.g. on a mobile device, required to register user 1002 with the identity verification system. In some embodiments, when user 1002 chooses to register with the identity verification system, user 1002 will be taken to an interface where user 1002 can input personal information required for the identity verification system to verify the user. In some embodiments, if user 1002 is registered with the identity verification system, user 1002 is prompted by identity verification platform 2000 to complete their profile information to be storage and used by identity verification platform 2000. In some examples, user 1002 may be presented with a graphical user interface requesting the profile information requested by identity verification platform 2000. In some embodiments, FIG. 18 is an illustrative example of a graphical user interface that may be presented to user 1002 to create a personal profile in identity verification platform 2000.

In step 1220, identity verification platform 2000 verifies the identity of user 1002 that sent the request to identity verification platform 2000 to register the company/organization 2020. In some embodiments, identity verification platform 2000 may request that user 1002 sign into the identity verification system, and if user 1002 has a valid log in to the identity verification system, identity verification platform 2000 ascertains that user 1002 has been previously verified by the identity verification system. In step 1220, once identity verification platform 2000 has verified user 1002, identity verification platform 2000 additionally verifies the relationship between user 1002 and company/organization 2020. In some embodiments, identity verification platform 2000 searches one or more databases, social media networks, registers, lists, or other sources of information to verify the relationship between user 1002 and company/organization 2020.

For example, identity verification platform 2000 may search on LinkedIn (LinkedIn Corporation, Palo Alta, CA) to see if user 1002 list company/organization 2020 as their current employer. In some examples, identity verification platform 2020 may search the company/organization 2020's website to determine if user 1002 is listed as an employee or team member of the company on that website.

In step 1230, identity verification platform 2000 verifies that company/organization 2020 is a legitimate company. In some embodiments, information which may be used to verify the legitimacy of company/organization 2020 may be available from trusted sources such as Bloomberg, Inc. (Bloomberg, New York City, NY), GlobeData (The Globe Program, Boulder, CO), ICD Research (ICD Research Limited, London, UK), MarketLine (MarketLine, Manchester, UK) PrivCo (PrivCo, New York City, NY), SGA (SGA, Boston, MA), ExecutiveTracker (Executive Trackers LLC, Los Gatos, CA), Timetric (Trimeric, London, UK), and World Market Intelligence (World Market Intelligence Limited, London, UK). In some embodiments, identity verification platform 2000 may verify that a company or organization is legitimate via a certificate exchange with a trusted authority that identifies the company or organization as legitimate. In some embodiments, identity verification platform 2000 may verify that a company or organization is legitimate based on the presence of a record in a distributed or centralized ledger corresponding to the company or organization, and, in some implementations, that the record is associated with a non-zero currency value. In some embodiments, once identity verification platform 2000 verifies that company/organization 2020 is legitimate, identity verification platform 2000 creates a record of the company in a database or storage.

In step 1240, user 1002 creates a request to invite connection 2025 to have a given relationship to or with company/organization 2020. In embodiments, user 1002 may create a request to invite existing or new employees to be team members of company/organization 2020. In some examples, user 1002 may create a request to invite connections 2025 to be advisors of company/organization 2020. In some embodiments, user 1002 may be presented with a graphical user interface, for example as shown in FIG. 29 , that may be used to invite a new connection. User 1002 may upload a photo of the new connection, for example from a file from a device of user 1002 or from a cloud storage In examples, user 1002 may invite connection 2025 using the email address of connection 2025. User 1002 may, as part of the invitation to connection 2025, specify the relationship of connection 2025 with company/organization 2020. In some examples, user 1002 may interact with a selection on a graphical user interface in order to cause identity verification platform 2000 to receive a request to invite connection 2025. For example, user 1002 may click with an “invite” button on a graphical user interface on user 1002's device.

In step 1250, responsive to receiving a request from user 1002 to invite connection 2025 to company/organization 2020, identity verification platform 2020 may transmit to connection 2025, a request for approval of the relationship between the company/organization 2020 and connection 2025. In some embodiments, identity verification platform 2000 sends a message to connection 2025 using the email address for connection 2025 that was provided by user 1002. In some examples, identity verification platform 2000 raises an alert or causes a notification to be sent from an application on connection 2025 s device, for example on an identity verification system application on the device of connection 2025. In embodiments, connection 2025 has already registered with the identity verification system and has an authenticated profile with the identity verification system. Connection 2025 may then be prompted by a message, such as an email message, a text message, or an in-app message, to log into the identity verification system to view the invitation. In examples, connection 2025 has not registered with the identity verification system. Connection 2025 may then be prompted with a message, such as an email message or a text message, to download the application for the identity verification system of the device of connection 2025 or may be presented with a link that connection 2025 can click on to traverse to a website of the identity verification system in order to register with the identity verification system and have their identity verified. In some embodiments, connection 2025 may only see the invitation from user 1002 once connection 2025 has been fully authenticated by the identity verification system.

In step 1260, connection 2025 may review the invitation from user 1002. In examples, connection 2025 may sign in to the identity verification system and see the invitation as a message or alert in identity verification system. In examples, when connection 2025 opens or selects the message or alert in the identity verification system, connection 2025 traverses to a website for identity verification platform 2000. In some examples, when connection 20205 opens or selects the message or alert in the identity verification system, an application for identity verification platform 2000 opens on connection 2025's device, and connection 2025 may view the invitation from user 1002 in the application. Connection 2025 may be able to select or open the invitation to view parameters and/or details of the invitation. In some examples, connection 2025 may be presented with the details of the relationship to the company/organization (for example, team member, advisor, employee, etc.), and the name of the user 1002 that invited connection 2025 to have a relationship with company/organization 2020. In embodiments, connection 2025 may approve or reject the relationship invitation from user 1002 with company/organization 2020. In embodiments, when connection 2025 approves or rejects the relationship invitation from user 1002, a message representing the approval or rejection is sent to identity verification platform 2000.

In step 1270, responsive to receiving the approval or rejection of the relationship with company/organization 2020 from connection 2025, identity verification platform 2000 transmits confirmation of the relationship of connection 2025 with company/organization 2020 to user 1002. In some embodiments, the confirmation is sent to user 1002 via the identity verification platform 2000 console and/or dashboard for the company/organization. In examples, identity verification platform 2000 may send a message to user 1002, for examples, and email message, a text message, or a message that triggers a notification on a device of user 1002, requesting that the user log on to identity verification platform 2000. In some embodiments, message to user 1002 may have a link that user 1002 may click on to be directed to the web dashboard for company/organization 2020 on identity verification platform 2000.

In step 1280, identity verification platform 2000 creates a custom badge representing the approved relationship between connection 2025 and company/organization 2020. In some embodiments, the badge may be rendered on a company/organization 2020 webpage, dashboard, or console on identity verification platform 2000. In some embodiments, FIG. 27 shows an illustration of badges for connections for company/organization 2020 rendered on identity verification platform 2020. In some examples, user 1002 of company/organization 2020 may export a badge of connection 2025, for example by clicking on the badge for connection 2025. In embodiments, the rendered badge on identity verification platform 2020 shows a picture for connection 2025, the name of connection 2025, the relationship between connection 2025 and company/organization 2020, the email address for connection 2025, and optionally any other profile information for connection 2025, for example a link to connection 2025's LinkedIn profile, or twitter feed, or any other social network feed for connection 2025. In embodiments, connections 2025 of company/organization 2020 may be organized on different pages according to the type of connection. For example, connections that are advisors to company/organization 2020 may be shown on one page, and connections that are team members of company/organization 2020 may be shown on a second page, and all connections of company/organization 2020 may be shown on a third page.

In a general overview, FIG. 13 depicts a method for creating and exporting a verified individual's badge on a company/organization 2020's website. User 1002 may send an invitation for a relationship between company/organization 2020 and connection 2025 (step 1310). User 1002 may receive an approval notification of the relationship between company/organization 2020 and connection 2025 (step 1320). In step 1330, user 1002 may export code for connection 2025 from the badge for connection 2025. User 1002 may import the code exported from the badge for connection 2025 to a website of company/organization 2020 (step 1340). In step 1350, connection 2025's badge representing the relationship between connection 2025 and company/organization 2020 may render on a website of company/organization 2020.

Referring to FIG. 13 in more detail, in step 1330, user 1002 may export code for connection 2025 from the badge for connection 2025, for example by clicking on the badge of connection 2025 on a dashboard or company console of identity verification platform 2000. In some examples, clicking on the badge of connection 2025 causes the download of code to a device of user 1002. In some examples, the downloaded code for the badge may include an html object tag, and Iframe, a flash object, or java code. User 1002 may import the exported code from the badge for connection 2025 to a website of company/organization 2020 (step 1340). In some examples, user 1002 may associate the exported badge code with a picture, a name, a biography, a description, and/or any other identification of connection 2025 on the website of company/organization. In step 1350, connection 2025's badge representing the relationship between connection 2025 and company/organization 2020 may render on a website of company/organization 2020. In some embodiments, connection 2025's badge will only render if the domain of the website that the code has been imported to matches the one or more domains that user 1002 registered as being associated with company/organization 2020, and which identity verification platform 2000 verified as being associated with company/organization 2020.

FIG. 14 depicts a method for registering a company with an identity verification platform. Identity management platform 2000 receives a request from user 1002 to register company/organization 2020 and ascertains that user 1002 does not have an account with the identity verification system. Identity verification platform 2000 prompts user 1002 to register with the identity verification system (step 1410). In some examples, identity verification platform 2000 presents a QR code to user 1002 (step 1420), for example a QR code as illustrated in FIG. 17 . In step 1430, user 1002 submits profile information to identity verification platform 2000, for example using a graphical user interface such as is illustrated in FIG. 18 . In some embodiments, user 1002 submits their profile information to the identity verification system instead of the identity verification platform 2000. In some examples, user 1002 uploads a photo to identity verification platform 2000, for example using a graphical user interface such as is illustrated in FIG. 19 . (step 1440). In some embodiments, user 1002 submits their photo to the identity verification system instead of the identity verification platform 2000. The identity verification platform 2000 receives a request from user 1002 to register company/organization 2020 (step 1450), for example using a graphical user interface such as is illustrated in FIG. 20 and in FIG. 21 and receives company details from user 1002 (step 1460). In some embodiments, user 1002 enters one or more of the name of company/organization 2020, an email address of company/organization 2020, a subdomain for a company profile URL that is based on the identity verification platform URL, and a phone number for company/organization 2020. Once the identity verification system has authenticated the user (step 1470), then the identity verification platform 2000 proceeds to verify and register the company/organization 2020 (step 1480).

In general overview, FIG. 15 illustrates an online verification system. In step 1505, a company representative (for example, user 1002) makes a request to register the company (for example, company/organization 2020) on identity verification platform 2000 dashboard. The request may be transmitted by a first device to a second device (e.g. from a mobile device, laptop computer, desktop computer, or other such device of the company representative, to a server or other device hosting identity verification platform 2000). In step 1510, identity verification platform 2000 verifies the identity of the company representative and verifies the relationship of the company representative to the company. The identity verification platform 2000 verifies that the company is a legitimate business in step 1520. As discussed above, verification of the identity of the representative, the relationship, and the legitimacy of the business may be performed via a certificate exchange with a trusted authority, identifying a record in a distributed or centralized ledger corresponding to the representative and/or business, via a web search for a social media profile or other profile associated with the representative or business, or by other such means. If the company is not a legitimate business the approval is blocked in step 1515. In step 1525, the company is approved, the company representative is approved, and the relationship between the company representative and the company is approved, and the company representative is authorized to do ID codes for the company. In step 1530, the company representative invites individuals with specified relationships to the company to be connections of the company. Upon receiving the invitation, the individual signs in to the identity verification platform and views the company's invitation in step 1540 and approves the relationship in step 1545. In step 1550, the company receives the approval notification. In some embodiments, invites with the claimed relationship between the company and individual are sent via email to specific individuals. In other embodiments, invites may be provided via push notifications to mobile devices, via a web page visited by the individuals, or any other such method. In examples, claimed relationships include but are not limited to advisor, investor, employee etc. In some embodiments, the individual creates their own biography in identity verification platform 2000 with such as their verified legal name.

In step 1555, identity verification platform 2000 generates customized code in the form of a badge for the individual. The company exports code from the individual's badge on the company dashboard of identity verification platform 2000 in step 1560. In step 1565, the company imports the code for the individual's badge on its website to enable verification that the claimed relationship to the individual is genuine. When a company attempts to render a badge, the identity verification platform verifies that the domain matches what was approved in step 1570. The badge can only be rendered on the web site within the domain or domains belonging to the company. In some embodiments, the identity verification platform is responsible for maintaining a list of domains that each badge is authorized to be rendered on. In step 1575, if the domain matches what was approved, the ID Codes verification badge for the individual is rendered on the company website. In step 1580, the third-party end user can click on the verification badge on the company website and in step 1585 the end user is traversed to an ID codes page on a different domain which verifies the relationship between the individual and the company. In examples, the ID codes page on the different domain is only valid for a short period of times, for example for 5 minutes, 10 minutes, 15 minutes, 30 minutes, 60 minutes, 2 hours, 12 hours, 24 hours, or any other time limited period, after which the page expires and cannot be viewed without the third-party end user again clicking on the ID codes verification badge for the individual on the company website. In some embodiments, the third-party user can see the individual's verified bio showing the company relationship. In step 1590, if the domain doesn't match what was approved, the badge fails to render.

Either the individual in step 1595 or the company in step 1596 may revoke the relationship at any time and as a consequence the badge will no longer render as shown in step 1590. All participants are notified if the relationship is revoked.

In some examples, JavaScript or other executable code that may be rendered by a web browser can be used for badge code. In some examples, an identity verification platform can automate various mechanisms to verify if a company is legitimate.

A system according to the current disclosure is particularly useful for an ICO or initial currency offering. In an ICO, the people that are behind the company offering the ICO are very important to the credibility of the offer. When a prospectus is produced for such an IPO, typically the board members or other high-profile members of the group putting the ICO together are displayed on the company's website that is doing the ICO. Just the association of important people with the ICO may encourage people to buy in, raising a significant amount of money for the company.

In some instances, companies may falsely represent that important people are associated with the ICO when they are not and have not agreed to be associated with the ICO. The company can put the people's pictures up on the website, and the general public has no way to know if this person's involvement is true or not.

The present disclosure can be used to verify that the person is associated with the company, or with the ICO, or more generally with any offering that is done online.

In some embodiments a company may register with an identity verification system. A validator will verify information about the company and attest to information about the company. The company may also invite people into the company, in whatever capacity the person would be related to the company. For example, the company may invite a person as a board member, or as an advisor, or as an auditor, or as a CEO. The validator will verify all the of the people that are invited to the company, both individually in their own right, and also in their association with the company. The validator will then be able to attest that the person is who they say they are, and also that they perform the function in the company that they were invited to.

Once the validator has attested to this information, the company is issued an ID code or badge for that individual. The company may display the ID code of badge on their website. In some embodiments, the ID code or badge may only be displayed on their website, or on a website associated with the company. In some embodiments, the validator has additionally validated the domains or URLs that are associated with the company, and the badge will only work on those URLs.

In some examples, the company may put a picture of the individual on the website and the picture may appear with a check mark beside it, or a badge icon, or any other representation, visual or audio, that indicates to a viewer of the website that that person has been authenticated by a validator. In some embodiments, a viewer of the website may click on the picture or click on the indication of validation, and the viewer may be taken to a webpage where they can read all the essential information about the individual. In some examples, the viewer can click on the indication of validation and be taken to the validator's website to view the information on the individual and to view the individual's association with the company that the validator has attested to. In some embodiments, the website viewer may be directed to another website where the ID codes are accessible, for example a website such as IDcodes.com.

The method also includes, responsive to receiving the identification of the selection, rendering, by the identity verification platform, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid.

In some implementations, the method includes verifying the identity of the first user and the relationship between the first user and the entity by verifying the existence of a record in a centralized or distributed ledger at an address corresponding to the entity. In some implementations, the method includes generating a transaction for recordation in a centralized or distributed ledger at an address based on the entity and the first individual, the presence of the first transaction in the centralized or distributed ledger indicating that the relationship between the first individual and the entity is legitimate. In a further implementation, the method includes generating the transaction by adding a non-zero value to a record in the centralized or distributed ledger at the address based on the entity and the first individual.

In some implementations, the method includes verifying the relationship between the first user and the entity by receiving a confirmation of the relationship between the first user and the entity via a communication channel separate from a communication channel via which the first request was received. In some implementations, the method includes rendering the verification that the relationship between the first individual and the entity is valid responsive to determining that validity of the relationship has not been revoked. In a further implementation, the method includes determining that validity of the relationship has not been revoked responsive to identifying a record in a centralized or distributed ledger at an address based on the entity and the first individual having a non-zero value.

In another aspect, the present disclosure is directed to a system for establishing a chain of relationships. The system includes a device, in communication with a device of a first user and a device of a first individual, comprising a network interface and a processor executing an identity verification platform. The network interface is configured to receive, from the device of the first user, a first request for registration comprising an identification of the first user, identification of an entity, and a relationship between the first user and the entity. The identity verification platform is configured to: verify, responsive to receipt of the first request, the identity of the first user and the relationship between the first user and the entity and verify that the entity is legitimate. The network interface is further configured to: receive, from the device of the first user, a first invitation for a relationship between the first individual and the entity; transmit to the device of the first individual, responsive to receiving the invitation for the relationship from the device of the first user, a second request for approval of the relationship between the first individual and the entity; receive, from the device of the first individual, approval of the relationship between the first individual and the entity; and transmit, to the device of the first user, confirmation of the relationship between the first individual and the entity.

In another aspect, the present application is directed to a method for verification of a chain of trust via a distributed or centralized ledger. The method includes receiving a request, by a validation system from a first device, for a validation badge, the request identifying a user and an entity. The method also includes retrieving, by the validation system, a record in a centralized or distributed ledger at an address corresponding to the user and entity.

D. Validating Policies of a Smart Contract

Transactions may be carried out on a centralized or distributed digital ledger. These transactions may employ a protocol smart contract containing an order (for something) and a means of paying for the order. The protocol smart contract may match to a counter-party and the order contained within is fulfilled. Such transactions do not account for any knowledge of the counter-party to the order requested. If the protocol smart contract and the centralized or distributed digital ledger is used for such transactions, then there is no method to ensure compliance with transaction policies. Some transactional protocols may have strict transaction policies, and organizations and/or individuals should comply with the transaction policies to participate in transactions within these transactional protocols. Since there is no way to ensure compliance, the protocol smart contract may not be suitable for participating in transactions requiring compliance with the transaction policies.

A solution is required which allows a party (organizations and/or individuals), engaging in a transaction within a transactional protocol defining transaction policies, to know with certainty that all parties to that transaction are allowed to participate. The solution requires all parties to abide by the transaction policies and all parties to be vetted by a trusted organization using a robust methodology. “Trusted organization” may refer to an organization which has the means to check credentials of a user or a second organization as well as authority within a transactional protocol to declare that the user or the second organization is able to interact with the transactional protocol. The “user” may refer to an individual or an organization that wants to carry out ecosystem transactions in a transactional protocol. A user may include a living person, a citizen, a legal entity, an autonomous device, a robot, a corporation, an organization, a company or partnership or other legal entity that can execute contracts, an agent or representative, an ambassador, a state, a city, a nation, a county, a party to a transaction, a group, a military, a government, a household, and the like.

The systems and methods of the present disclosure enable a user to carry out ecosystem transactions via a protocol smart contract on a centralized or distributed digital ledger. As discussed above, a “digital ledger” may refer to a digital record of who-owns-what. A digital ledger may be a centralized digital ledger or a distributed digital ledger. A centralized digital ledger or a centralized database is a system where data is stored in a master database with a single point of control, i.e., there exists a party that alone acts on behalf of clients to modify the system state. A distributed digital ledger is fundamentally different from a centralized digital ledger. In a distributed digital ledger, any party or node on a network has access to the digital ledger. Authorization, rather than being a function that is added onto the system at the end, is built into the lowest level of the stack. The distributed digital ledger is replicated among many different nodes in a peer-to-peer network, and a consensus algorithm ensures that each node's copy of the digital ledger is identical to every other node's copy. Asset owners must use cryptographic signatures to make transactions on a distributed digital ledger. Cryptocurrencies, such as Bitcoin and Ether, make use of a distributed digital ledger called a blockchain. A user may send a request to a trusted organization to verify credentials of the user and to validate that the user may engage in an ecosystem transaction within a transactional protocol. “Credentials” may refer to a set of data points associated with a user which may be provided by the user or may be obtained independently, checked, and formally validated by a trusted organization to be true. The credentials may indicate that the user abides by transaction policies set by a transactional protocol and thus may be allowed to make ecosystem transactions on that transactional protocol. Examples of a credential may include nationality, social security number, place of residence, place of birth, age, credit rating, account balance. The credentials may also include physical documents representing the set of data points, such as a passport, a social security card, a green card, a driver's license, a college degree, a diploma, a training certification, a marriage license, a court document, a title, a deed, a chain of title, and the like.

The trusted organization may receive the credentials and a cryptographically secure identity associated with the user. Based on the credentials provided by the user, the trusted organization may carry out a vetting process on the user in accordance with transaction policies defined by the transactional protocol. When the credentials of the user are verified to a predefined level of satisfaction, the user may be considered as abiding by the transaction policies and the trusted organization may issue a token to the user representing that the transaction policies are followed. When the user enters an ecosystem transaction, the user may provide the token along with other ecosystem transaction details. The token may be checked for validity and if it is controlled by the user. If the token is valid and controlled by the user, the ecosystem transaction may be included in the centralized or distributed digital ledger.

FIG. 35 depicts an implementation of some of an architecture of system 3500 for validation of policies of a smart contract on a centralized or distributed digital ledger in an ecosystem, according to some embodiments. As shown in FIG. 35 , system 3500 may interconnect a plurality of participants such as devices, systems, components, resources, facilities, and the like in communication with one another via network 3512.

System 3500 may include user 3502 (also generally referred to as user computing device 3502), trusted organization 3504 (also generally referred to as trusted organization device 3504 or trusted organization site 3504), third-party organization 3506, centralized or distributed ledger 3508, digital wallet 3510, and network 3512 enabling communication between the system components for information exchange. In some implementations, “digital wallet” may refer to a software or hardware, or a combination of software and hardware asset that stores a collection of keys that controls digital assets or funds. The digital wallet may allow a user to make electronic commerce or ecosystem transactions easily and securely. “Ecosystem transaction” may refer to a transaction on a centralized or distributed digital ledger which is associated with a specific ecosystem or group of entities that are working in association (explicitly or implicitly, and directly or indirectly), have adopted similar policies, etc. An example of a specific ecosystem is a decentralized finance (DeFi) ecosystem. Other examples of ecosystems include an industry, a marketplace, a collection of similar units (e.g. product vending machines whether by the same or different manufacturers), etc.

Centralized or distributed ledger 3508 may include protocol smart contract 3514 and gateway smart contract 3516. As discussed above, “smart contract” may refer to a computer program or a transaction protocol that automatically executes, controls, or documents events and actions according to terms of a contract or an agreement. “Gateway smart contract” may refer to a smart contract that is associated with processing of tokens. “Protocol smart contract” may refer to a smart contract that is associated with the processing of a transactional protocol.

According to an implementation, user 3502 may correspond to any computing device used by a user. In some embodiments, user 3502 may refer to an individual or an organization that wants to carry out ecosystem transactions in a transactional protocol. User computing device 3502 may be any computing device, such as a desktop computer, a laptop, a tablet computer, a mobile device, a Personal Digital Assistant (PDA) or any other computing device. In an implementation, user computing device 3502 may be a device, such as a client device.

According to an implementation, trusted organization 3504 may correspond to a trusted organization site or device, an organization, a person, a computer-implemented algorithm, a centralized or a decentralized computing system, and the like. Trusted organization 3504 may be configured to validate credentials of user 3502 as well as authority within a transactional protocol to declare that user 3502 is able to interact with the transactional protocol.

According to an implementation, third-party organization 3506 may correspond to a third-party organization site or device, an organization, a person, a computer-implemented algorithm, a centralized or a decentralized computing system, and the like. Third-party organization 3506 may be configured to validate the credentials of user 3502 under a control of trusted organization 3504. In an example, the credentials of user 3502 may be validated by a combination of both trusted organization 3504 and third-party organization 3506.

According to an implementation, digital wallet 3510 may correspond to a digital wallet provider site or device, a computer-implemented algorithm, a centralized or a decentralized computing system, and the like. Digital wallet 3510 may store a collection of keys, such as a public and private key pair associated with user 3502 that controls digital assets or funds associated with user 3502. Digital wallet 3510 may allow user 3502 to make electronic commerce or ecosystem transactions easily and securely. A digital wallet provider may store digital wallet 3510 associated with user 3502 on a server computing device, such that information stored in digital wallet 3510 may be easily accessed from anywhere. User 3502 may access the information stored in digital wallet 3510 via a website or a computer program application running on user computing device 3502. In an embodiment, digital wallet 3510 associated with user 3502 may exist in user computing device 3502. In an embodiment, digital wallet 3510 may be backed up to a third-party website, application, or service.

In aspects of the present disclosure, cryptography techniques defined by PKI and by Elliptic Curve Cryptography (ECC) may be used. An asymmetric or public key cryptography may use a pair of public and private keys (public-private key pairs) to encrypt and decrypt data. The public-private key pairs are large numbers paired together, but are not identical. One key in the public-private key pair, i.e., the public key, may be shared with every participant in a transaction. The other key in the public-private key pair, i.e., the private key is kept secret. Either of the public key or private key may be used to encrypt a message, and the other key is used for decryption. All participants in a transaction may have a corresponding public-private key pair. For example, user 3502 may have a public-private key pair, trusted organization 3504 may have a public-private key pair, and digital wallet 3510 may have a public-private key pair. In an example, a technique described by ECC may be used to generate public-private key pairs. In an embodiment, hashing may also be used. A cryptographic hash function or “hash” is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size. It is designed to be a one-way function. The only way to recreate input data from a cryptographic hash function's output is to attempt a brute-force search of possible inputs to determine if they produce a match. An example of a hash function is SHA-256.

According to aspects of the present disclosure, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be a server or computing device owned or managed or otherwise associated with an organization or any entity authorized thereof. According to some embodiments, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be implemented in a variety of computing systems, such as a mainframe computer, a server, a network server, a laptop computer, a desktop computer, a notebook, a workstation, and any other computing system. In an implementation, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be implemented in a server. In some implementations, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be implemented by a device. In some embodiments, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be implemented as a part of a cluster of servers. In some embodiments, trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be implemented across a plurality of servers, thereby, tasks performed by trusted organization 3504, third-party organization 3506, and digital wallet 3510 may be performed by the plurality of servers. These tasks may be allocated among the cluster of servers by an application, a service, a daemon, a routine, or other executable logic for task allocation.

According to an implementation, centralized or distributed ledger 3508 may refer to a digital record of who-owns-what. One or more participants of system 3500 may have access to centralized or distributed ledger 3508. Centralized or distributed ledger 3508 may be an electronic ledger that includes a list of verified transactions. For example, for digital cryptocurrencies such as Bitcoin and Ether, centralized or distributed ledger 3508 is a distributed ledger referred to as a blockchain. Protocol smart contract 3514 and gateway smart contract 3516 may be stored in centralized or distributed ledger 3508 at an address or in an account. Part or all of centralized or distributed ledger 3508 may be downloaded or cached by any of the participants in system 3500 for offline use. Any participant may download centralized or distributed ledger 3508 on a periodic basis when they are connected online. Centralized or distributed ledger 3508 may be delivered on a periodic or one-time basis to the one or more participants via electronic mail, file transfer protocol, postal mail, delivery service, or private delivery channels operated by the respective participants. In an example, the Bitcoin blockchain may be used as centralized or distributed ledger 3508. In another example, a different centralized or distributed ledger 3508 may be used instead of the Bitcoin blockchain. Centralized or distributed ledger 3508 may be accessed from a cached offline store.

According to some embodiments, user computing device 3502 may include processor 3518 and memory 3520. In an example, processor 3518 and memory 3520 of user computing device 3502 may be CPU 1021 and main memory 1022, respectively, as shown in FIGS. 10C and 10D. User computing device 3502 may also include user interface, such as a keyboard, a mouse, a touch screen, a haptic sensor, voice-based input unit, or any other appropriate user interface. It shall be appreciated that such components of user computing device 3502 may correspond to similar components of computing device 1000 in FIGS. 10C and 10D, such as keyboard 1026, pointing device 1027, I/O devices 1030 a-n and display devices 1024 a-n. User computing device 3502 may also include display, such as a screen, a monitor connected to the device in any manner, or any other appropriate display. In an implementation, user computing device 3502 may display received content for the user using the display and is able to accept user interaction via the user interface responsive to the displayed content.

According to some embodiments, trusted organization device 3504 may include processor 3522 and memory 3524. For example, processor 3522 and memory 3524 of trusted organization device 3504 may be CPU 1021 and main memory 1022, respectively, as shown in FIGS. 10C and 10D.

In an implementation, ecosystem transactions may be performed using protocol smart contract 3514. Protocol smart contract 3514 may be stored on centralized or distributed ledger 3508 at an address or in an account. In an embodiment, the address or account of protocol smart contract 3514 may be a known value by which a relevant protocol smart contract may be accessed. Protocol smart contract 3514 represents a transactional protocol for receiving, validating, and processing an ecosystem transaction. For a given ecosystem transaction, the transactional protocol may include transaction policies (or rules) that all users transacting with that ecosystem transaction must adhere to. In an example, the ecosystem transaction may be a Decentralized Finance (DeFi) system. “Decentralized finance” or “DeFi” may refer to a blockchain-based form of finance that does not rely on central financial intermediaries such as brokerages, exchanges, or banks to offer traditional financial instruments. Instead, the DeFi uses smart contracts on blockchains.

In another example, a transaction policy (sometimes referred to as a policy, rule, condition, guideline, or by similar such terms or combinations of terms) of the DeFi system may be that a user may not be resident of the United States to enter a transaction on the DeFi system. Transaction policies may comprise a set or aggregation of one or more conditions (including positive or required conditions and/or negative conditions or those that are required not to be present), and may be stored in any suitable manner. For example, in some implementations, a transaction policy may comprise a set of characteristics or variables (e.g. demographic information, time or date information, etc.) and corresponding thresholds or values (e.g. binary ones or zeros or yes/no identifications, minimum ages, number of days, etc.). Transaction policies may be stored in any suitable format, e.g. XML files, data arrays, flat files, etc.

In an implementation, trusted organization 3504 may validate the credentials of user 3502 to ensure that user 3502 satisfies all the transaction policies of a transactional protocol (e.g. that conditions or variables corresponding to user 3502 satisfy corresponding values or thresholds, such as an age of the user being above a threshold, or a location of the user being within a specified country). If the credentials of user 3502 are verified to a predefined level of satisfaction, trusted organization 3504 may issue a token. For example, in some implementations, transaction policy may itself be associated with a satisfaction threshold, and the system may determine whether a number or percentage of the conditions of the transaction policy exceeding the satisfaction threshold are satisfied (e.g. 8 out of 10 conditions satisfied to exceed a satisfaction threshold of 75%, or any other such value). In some implementations, each condition of a transaction policy may be associated with a score value, and the satisfaction threshold may comprise an aggregated score threshold. For example, a first condition, such as detecting a positive match between a fingerprint captured via a biometric scanner and a previously stored fingerprint, may have a high score; and a second condition, such as a location of the device corresponding to a predetermined location, may have a low score. Satisfying a combination of conditions may result in an aggregate score exceeding the satisfaction threshold. Tokens issued responsive to the credentials being verified may represent user 3502, the transaction policies and the transactional protocol. The token may comprise an alphanumeric string, hash value, or any other such data.

FIG. 36 depicts sequence diagram 3600 for user 3502 to acquire a token from trusted organization 3504, according to some embodiments.

In an implementation, user 3502 may generate a first public-private key pair to be associated with the token. In an embodiment, the first public-private key pair may be stored in digital wallet 3510 associated with user 3502.

As shown in FIG. 36 , at step 3602, user 3502 may send a request to trusted organization 3504 to verify credentials of user 3502 and validate that user 3502 may engage in an ecosystem transaction within a transactional protocol. The request may include the credentials to be verified and a cryptographically secure identity.

In an embodiment, the cryptographically secure identity is a first public key in the first public-private key pair to which user 3502 can prove ownership of a first private key in the first public-private key pair. In an embodiment, the credentials may be used to determine that user 3502 complies, in part or in totality, with transaction policies defined by the transactional protocol. Examples of the credentials may include, but are not limited to, passport information, residency permit information, national identity card information, driver's license information, social security number, educational certificates, birth certificate, marriage certificate, email contact details, cell phone contact details, proof of residential address, a court document or a legal document, a deed, and proof of employment. The credentials required to determine compliance may vary depending on the type of ecosystem transaction and/or transaction policies defined by various transactional protocols. The credentials may be provided in any suitable format, including as XML data, concatenated data strings, parameter-value pairs, text, or any other such format.

At step 3604, trusted organization 3504 may communicate a request for corroborating data to one or more third-party organizations 3506.

In an embodiment, trusted organization 3504 may receive a part of or all the credentials from one or more sources of information other than receiving from user 3502. Such one or more sources of information may be third-party organization 3506 or other organizations in communication with third-party organization 3506. The corroborating data may include a part of or all the credentials of the user and any additional or supporting information that may be required to determine that user 3502 complies, in part or in totality, with transaction policies defined by the transactional protocol. In an embodiment, trusted organization 3504 may not send the request for the corroborating data (step 3604) to third-party organization 3506, when trusted organization 3504 is capable of independently determining that user 3502 complies with transaction policies defined by the transactional protocol, i.e., trusted organization 3504 does not require the corroborating data to determine that user 3502 complies with transaction policies.

At step 3606, third-party organization 3506 may communicate the corroborating data to trusted organization 3504.

In an embodiment, trusted organization 3504 may generate a second public-private key pair to be associated with a token. The second public-private key pair may represent trusted organization 3504 and the second public-private key pair may be common for all tokens issued by trusted organization 3504.

At step 3608, trusted organization 3504 may validate the credentials of user 3502. Trusted organization 3504 may use one or more validation steps to validate the credentials of user 3502. In an example, trusted organization 3504 may text, email, call, or message user 3502 using contact details such as the email contact details, and the cell phone contact details provided by user 3502 to continue with or complete the validation of the credentials. Trusted organization 3504 may use a preferred communication channel requested by user 3502. In another example, trusted organization 3504 may send a physical postcard or mail to the residential address provided by user 3502. In an embodiment, trusted organization 3504 may require user 3502 to share a code, provided on the text, email, call, message, physical postcard, or mail, with trusted organization 3504 to continue with or complete the validation of the credentials. In another example, trusted organization 3504 may require user 3502 to prove that user 3502 owns or controls something by providing a verifiable title or a password. In another example, trusted organization 3504 may provide information to user 3502 on one communication channel of user 3502 and require that user 3502 provides the same information to trusted organization 3504 on another communication channel of the user 3502 to continue with or complete the validation of the credentials. In an example, trusted organization 3504 may use a Know Your Customer (KYC) methodology to validate the credentials of user 3502. In another example, trusted organization 3504 may use a Know Your Business (KYB) methodology to validate the credentials of user 3502. “Know your business” may refer to guidelines and processes by which an individual or a first organization may verify and validate identity, suitability, and risks of a second organization when engaging in a business relationship with the second organization. “Know your customer” may refer to guidelines and processes by which a first individual or an organization may verify and validate identity, suitability, and risks of a second individual when engaging in a business relationship.

In an embodiment, the validation of the credentials may be carried out by trusted organization 3504 or by another party under the control of trusted organization 3504, such as third-party organization 3506, or by a combination of both.

In an example, and where user 3502 is an individual, the transaction policies required by the transactional protocol may be verified by a KYC methodology. In another example, and where user 3502 is an organization, the transaction policies required by the transactional protocol may be verified by a KYB methodology. As discussed above, validating transaction policies may comprise evaluating a Boolean expression or values for a series or set of conditionals (e.g. determining if characteristics or values of the credentials match corresponding values or thresholds). In some implementations, validating transaction policies may comprise determining whether a number or percentage of credentials have been validated or match the policies above a satisfaction threshold, or whether an aggregate score for the credentials or characteristics exceeds a satisfaction threshold.

In an embodiment, trusted organization 3504 may verify that user 3502 controls the first public key included in the request received (step 3602) from user 3502. To verify that that user 3502 controls the first public key, trusted organization 3504 may generate a challenge cryptographic nonce. “Cryptographic nonce” may refer to an arbitrary number that is used only once in a cryptographic communication. The cryptographic nonce may be a random or pseudorandom number and may include a timestamp to ensure that the cryptographic nonce is used only once. The cryptographic nonce may be used to introduce more entropy into a hash.

In an embodiment, the challenge cryptographic nonce may be generated by a cryptographic nonce generation algorithm and may include a timestamp. In an embodiment, the challenge cryptographic nonce may be generated through repeated hashing of a random or pseudo-random value. The challenge cryptographic nonce may be generated using a software or using a dedicated hardware circuit that supports encryption or using a combination of both.

At step 3610, trusted organization 3504 may generate and send the challenge cryptographic nonce to user 3502. In response to receipt of the challenge cryptographic nonce, user 3502 may sign the challenge cryptographic nonce using a cryptographical signing protocol and the first private key corresponding to the first public key being verified.

At step 3612, user 3502 sends the signed challenge cryptographic nonce to trusted organization 3504. If trusted organization 3504 determines that the first private key used to sign the challenge cryptographic nonce corresponds to the first public key being verified, trusted organization 3504 may verify that user 3502 has current control over the first public key in the first public-private key pair.

When the credentials of user 3502 are verified to a predefined level of satisfaction (e.g. based on number of verified credentials, percentage of verified credentials, score of verified credentials, etc., as discussed above), user 3502 may be considered as abiding by the transaction policies defined by the transactional protocol and trusted organization 3504 may validate that the credentials of user 3502 satisfy the transaction policies and that the credentials are legitimate.

At step 3614, trusted organization 3504 may create a token including the first public key associated with user 3502 and a token identifier. In an embodiment, the token identifier may represent that user has presented credentials that comply with transactional policies corresponding to the transactional protocol. In an embodiment, the token identifier may include an identifier representing the issuing organization, i.e., trusted organization 3504.

At step 3616, trusted organization 3504 may include a period of validity to the token. The period of validity represents a duration for which the token is valid. Trusted organization 3504 may determine the period of validity over which user 3502 may use the transactional protocol without further verification or validation. During the period of validity of the token, user 3502 may be allowed to make ecosystem transactions that lie within the transactional protocol for which the token is created without further validation of the credentials of user 3502. In an example, the period of validity may not be limited. In an example, during the period of validity, user 3502 may be allowed to make a maximum of a predetermined number of ecosystem transactions that lie within the transactional protocol for which the token is created.

At step 3618, trusted organization 3504 may generate a transaction to issue the token. Trusted organization 3504 may associate the token with both the first public key of user 3502 and the second public key of trusted organization 3504 and then may issue the token. Issuing a token is described in further detail with reference to FIG. 4 .

At step 3620, trusted organization 3504 may inform user 3502 of the token (e.g. by transmitting an identifier, pushing a notification to a device, providing a receipt, etc.).

According to aspects of the present disclosure, a token may be a representation of information which may include one or more of: a) an identifier associated uniquely to transaction policies defined by a transactional protocol represented by that token, b) a status of the token such as currently valid, suspended, and revoked, c) a period of validity for which the status of the token is valid, d) an identifier representing organization that issued the token, i.e., trusted organization 3504 in the present disclosure.

In an embodiment, the token may be represented by data stored in gateway smart contract 3516. In an example, gateway smart contract 3516 may be stateful, i.e., contain data representing many users. In another example, gateway smart contract 3516 may be stateless, i.e., there may be a plurality of identical gateway smart contracts 3516 that each include data representing a single user. In all cases, identity of user 3502 is the first public key and is provided alongside or as part of the credentials of user 3502. Prior to an issue of the token, trusted organization 3504 may verify that user 3502 has control of the first public key and verify the validity of the credentials of user 3502. The token may be associated uniquely with the first public key of the user.

In an example, address of gateway smart contract 3516 may be a predetermined address associated with the transaction policies that gateway smart contract 3516 provides the token to represent. In another example, the address of gateway smart contract 3516 may be a predetermined address associated with a management of tokens. In another example, the address of gateway smart contract 3516 may be determined by hashing information provided by user 3502 to trusted organization 3504 that issues the token. The information that is hashed to determine the address of gateway smart contract 3516 may include the first public key of user 3502.

An example of stateful gateway smart contract 3516 in pseudocode may be:

  Gateway Contract( ) State:  Gateway TokenTable Functions:  addToken(walletAddress)  revokeToken(walletAddress)  toggleTokenFrozen(walletAddress)  . . .

where GatewayTokenTable is the “state” of the contract and may comprise multiple rows representing different users with the following columns:

-   -   WalletAddress (address of digital wallet 3510 of user 3502 to         which the token has been issued)     -   Trusted Organization (identifier representing trusted         organization 3504 that issued the token)     -   TokenState (status of the token)     -   TokenlssuedAt (date and/or time at which the token is issued)     -   TokenExpiresAt (date and/or time at which the token expires,         i.e., no longer valid)

In an example, the state of gateway smart contract 3516 (for example, GatewayTokenTable) may be public, and read-only outside gateway smart contract 3516. Only gateway smart contract 3516 may edit the state but anyone can read the state (for example, to check if a particular user's digital wallet has a token). In an example, gateway smart contract 3516 may govern who has permission to modify its state, i.e., who is permitted to call the functions associated with gateway smart contract 3516. In an example, stateful gateway smart contract 3516 may be used with the Ethereum® blockchain.

An example of stateless gateway smart contract 3516 in a pseudocode may be:

  Gateway Contract( ) Functions:  addToken(walletAddress):TokenAccount  revokeToken(TokenAccount)  toggleTokenFrozen(TokenAccount)  . . .

where TokenAccount may be a class, an instance of which represents a single token. addToken may create a TokenAccount and may return it as the output. Each other function may take an instance TokenAccount as an input.

Gateway smart contract 3516 is a stateless gateway smart contract 3516 as there is no data within gateway smart contract 3516. In an example, to determine whether a user holds a token, the user may provide details of a TokenAccount that holds or represents the token, and that TokenAccount may be queried to verify that the token is valid. Gateway smart contract 3516 in a stateless model may govern who can generate TokenAccounts but may not store a list of all TokenAccounts. In an example, stateless gateway smart contract 3516 may be used with the Solana™ blockchain.

FIG. 37 depicts flowchart 3700 for issuing a token, according to some embodiments.

As shown in FIG. 37 , at step 3702, trusted organization 3504 may determine an address in centralized or distributed ledger 3508 of gateway smart contract 3516 which manages tokens for transaction policies. In an embodiment, the address may be a predetermined address. In another embodiment, the address may be a random address. In another embodiment, the address may be determined by hashing information provided by user 3502. For example, in one implementation, a user identifier (e.g. account name or other identifier) may be hashed to generate an alphanumeric code that may be used as an address or index to the ledger. Because the address or index may be more difficult to remember than the user identifier, such implementations may provide an easy method to dynamically regenerate the address when needed by applying the same hash algorithm to the user identifier. In some examples, a gateway smart contract 3516 may be used that can be either a stateless or a stateful gateway smart contract model.

At step 3704, trusted organization 3504 may create a transaction that includes one or more of: the first public key of user 3502, contact detail(s) of user 3502, the period of validity of the token to be issued, the second public key of trusted organization 3504, an identifier representing type of the token (i.e., the identifier associated uniquely to the transaction policies defined by the transactional protocol represented by the token).

At step 3706, trusted organization 3504 may cryptographically sign the transaction and send the cryptographically signed transaction for processing into centralized or distributed ledger 3508.

At step 3708, gateway smart contract 3516, which manages tokens for transaction policies may execute the transaction to issue the token.

At step 3710, on confirmation of issuance of the token, trusted organization 3504 may inform user 3502 that the token has been issued. In an embodiment, gateway smart contract 3516 may inform user 3502 that the token has been issued via the contact detail(s) of user 3502.

According to aspects of the present disclosure, centralized or distributed ledger 3508 may be a blockchain, and the issuance of the token may be confirmed if the transaction executed by gateway smart contract 3516 is confirmed by centralized or distributed ledger 3508. Centralized or distributed ledger 3508 may be replicated among a plurality of nodes in a peer-to-peer network.

In an embodiment, centralized or distributed ledger 3508 may confirm the transaction when one or more conditions are met. The one or more conditions may include: a) a validator/miner node of the plurality of nodes takes the transaction and adds it to a block in the blockchain, b) the validator/miner node broadcasts the block to the rest of the plurality of nodes in the blockchain, c) sufficient or a predetermined amount of time has passed, and d) sufficient or a predetermined number of new blocks are added to the blockchain after this block. After the predetermined amount of time has passed or the predetermined number of new blocks are added, it may be highly unlikely that the blockchain is later changed to exclude the transaction.

In an embodiment, trusted organization 3504 may submit the transaction to the blockchain, via an Application Programming Interface (API) that broadcasts the transaction to a known set of nodes, i.e., the plurality of nodes. Trusted organization 3504 then waits for the API to report that the transaction has been added to the blockchain and has a predetermined number of confirmations. In an embodiment, the predetermined number of confirmations may be greater than or equal to half of the number of the plurality of nodes. In an implementation, the report may take a few seconds, a few minutes, or a few hours depending on the blockchain.

According to aspects of the present disclosure, after a token has been issued by trusted organization 3504, the token may be further processed by trusted organization 3504. The further processing may change a state of the token. Trusted organization 3504 may expire, freeze, thaw, revoke, reissue, and renew the token. To change the state of the token, trusted organization 3504 may send a transaction that details required processing to gateway smart contract 3516 associated with management of the tokens. The transaction may contain details of trusted organization 3504. In an embodiment, the details of trusted organization 3504 is the second public key of trusted organization 3504. In examples, and where it is appropriate, the transaction may include a validity time (or a period of validity) for the new state of the token. The transaction is cryptographically signed by trusted organization 3504 and sent for processing to centralized or distributed ledger 3508.

In an embodiment, trusted organization 3504 may expire the token. In an example, to expire the token, trusted organization 3504 may set the period of validity to zero.

In an embodiment, trusted organization 3504 may freeze the token. In an example, trusted organization 3504 may specify a duration of time for which the token is frozen. In another example, a frozen token remains frozen until it is reactivated (or thawed).

In an embodiment, trusted organization 3504 may thaw the token which has been frozen. In an example, trusted organization 3504 may thaw the token without providing any other information. In another example, the credentials of user 3502 that owns the token are validated again prior to thawing the token.

In an embodiment, trusted organization 3504 may revoke the token. In an example, the token may be removed completely. In another example, a revoked token may remain, but the revoked token is marked as revoked. In an example, the revoked token may be reissued by trusted organization 3504 after the credentials of user 3502 have undergone a complete validation. In another example, the revoked token may not be reissued and the first public-private key pair of user 3502 associated with the token may not be issued the same token again.

In an embodiment, trusted organization 3504 may reissue a token that has been revoked. The credentials of user 3502 that owns the token may be validated again prior to reissuing the token.

In an embodiment, trusted organization 3504 may renew a token that has expired. In an example, the token may be renewed by a complete validation of the credentials of user 3502. In another example, trusted organization 3504 may not require any new credentials and may renew the token.

In an embodiment, trusted organization 3504 may freeze or revoke a token if an ecosystem transaction is made where one or more of the transaction policies that are represented by the token are not met. For example, if one of the transaction policies require the ecosystem transaction to be initiated outside of the United States but IP address of a computing device on which the ecosystem transaction is initiated shows that the computing device is within the United States, trusted organization 3504 may freeze or revoke the token. Once the token is frozen or revoked, a new validation process with trusted organization 3504 may be required to thaw or renew the token. In another example, the token may be frozen for a period of time and the token may be thawed after that period of time has expired.

In an embodiment, user 3502 may correspond to an organization and the organization provides the credentials to trusted organization 3504 for validation against the transaction policies of the transactional protocol. In an example, a process that validates the credentials of the organization is Know Your Business (KYB) methodology. In such an embodiment, digital wallet 3510 may be associated with the organization.

In an embodiment, digital wallet 3510 may be source of an ecosystem transaction and there may not be any check or restriction required for an individual that controls digital wallet 3510.

In another embodiment, an ecosystem transaction may require proving that not only the organization associated with digital wallet 3510 has a token but also an individual using or controlling digital wallet 3510 is also validated against the transaction policies of the transactional protocol. In such an embodiment, the individual may also provide credentials to trusted organization 3504 and trusted organization 3504 may validate the credentials of the individual as described with reference to FIG. 3 . Trusted organization 3504 may then issue a token to the individual associated with a public key provided by the individual as part of the credentials. In an example, a public-private key pair may be stored in digital wallet 3510 and may be used to validate the ecosystem transaction. In another example, user 3502 may be required to provide both an organization token and an individual token as part of the ecosystem transaction. In a further example, a new gateway smart contract 3516 may be implemented, which checks the validity of any number of tokens provided as input (for example, according to a set of policies, all tokens must be valid, or M-from-N tokens must be valid) and generates as an output, a single token which may form an input to protocol smart contract 3514.

In an embodiment, the organization may be permitted to issue digital wallets at its own discretion (for example, to individuals authorized by the organization). In such an embodiment, a proof of ownership of a valid token by the organization may alone be sufficient evidence for trusted organization 3504 to issue an identical token to the individual. Alternatively, in such an embodiment, the individual may be required to provide credentials to be validated by trusted organization 3504 along with the token already issued by trusted organization 3504. If the credentials are validated by trusted organization 3504 against the transaction policies, a token will be issued to the individual by trusted organization 3504. In an embodiment, the issued token may be associated with the individual's digital wallet as issued by the organization.

FIG. 38 depicts sequence diagram 3800 for user 3502 to engage in the ecosystem transaction, according to some embodiments.

Once the token is issued, user 3502 may engage with the transactional protocol and initiate ecosystem transactions associated with the transactional protocol.

At step 3802, user 3502 may generate the ecosystem transaction within the transactional protocol. The ecosystem transaction may refer to a set of information that includes one or more of: the transactional protocol, an order, a means to pay for the order, and the token that represents user 3502 complies with the transaction policies required by the transactional protocol.

In an example, the generated ecosystem transaction may include a set of information. In another example, the set of information may be stored elsewhere, for example, in gateway smart contract 3516 in centralized or distributed ledger 3508, and the generated ecosystem transaction provides reference to the set of information. In another example, the generated ecosystem transaction may include a part of the set of information and provide reference to remaining part of the set of information.

In an embodiment, the generated ecosystem transaction may not directly provide a reference to the token. In such an embodiment, the generated ecosystem transaction may refer to an identifier associated with user 3502. For example, the generated ecosystem transaction may refer to the first public key stored in digital wallet 3510 associated with user 3502. The first public key may be used to determine from the gateway smart contract 3516 that user 3502 holds the token for the transactional protocol.

In an embodiment, the transactional protocol, to which the ecosystem transaction is directed to, may be represented by protocol smart contract 3514. In such an embodiment, protocol smart contract 3514 may be a stateful protocol smart contract.

In an embodiment, the transactional protocol may be represented by the token and protocol smart contract 3514 to which the ecosystem transaction is directed to. In such an embodiment, protocol smart contract 3514 may be a stateless protocol smart contract.

In an embodiment, centralized or distributed ledger 3508 may store a plurality of protocol smart contracts having the same or similar functionality but representing different transactional protocols.

At step 3804, user 3502 may cryptographically sign the ecosystem transaction using a cryptographic signature and send the cryptographically signed ecosystem transaction for processing to centralized or distributed ledger 3508. In an embodiment, the ecosystem transaction is signed with the same private key that is associated with the token. In an embodiment, this private key is the first private key of user 3502.

In an embodiment, the cryptographic signature (or a digital signature) is used to prove that a party, i.e., user 3502, has generated a piece of digital information. The cryptographic signature is achieved within PKI by the party encrypting the piece of digital information with a private key associated with the party. The encrypted piece of digital information may be decrypted by a corresponding public key to recover the piece of digital information. Since the private key is known only by the party and the public key is known to every other participant involved in a transaction, the transaction is proved reliable to everyone that the party has generated the piece of digital information. In an embodiment, Elliptic Curve Digital Signature Algorithm (ECDSA) may be used to realize cryptographic signatures.

At step 3806, user 3502 may submit the cryptographically signed ecosystem transaction. The cryptographically signed ecosystem transaction may be received by a validating node of the plurality of nodes having replicated or having access to centralized or distributed ledger 3508. The validating node may check the cryptographical signature of the ecosystem transaction for validity. In an embodiment, validity is confirmed if the validating node asserts, by use of the first public key of user 3502, that the first private key of user 3502 was used to sign the ecosystem transaction and that the ecosystem transaction was not tampered with.

At step 3808, protocol smart contract 3514 referenced by the ecosystem transaction may be executed.

At step 3810, the token may be validated by gateway smart contract 3516. The token may be validated to check if the token is present (or exists), the token belongs to user 3502, the token is currently valid, and the token represents the transaction policies required for the transactional protocol. In an embodiment, ownership of the token is validated by checking that the token is associated with the first public key of user 3502 (e.g. by decrypting the token with the public key and verifying that the decrypted token comprises a validating code or other expected identifier, or by any other similar methods).

At step 3812, the ecosystem transaction may be accepted by protocol smart contract 3514 and the order included in the ecosystem transaction may be executed.

At step 3814, the ecosystem transaction may be added to centralized or distributed ledger 3508.

At step 3816, user 3502 may be informed that the ecosystem transaction has been executed and corresponding entry has been added to centralized or distributed ledger 3508.

In an embodiment, a first token may represent a first set of transaction policies, and a second token may represent a second set of transaction policies. The transactional protocol may require evidence that compliance for both the first set of transaction policies and the second set of transaction policies have been proven. This may be carried out by an intermediate gateway smart contract or other processing which accepts the first token and the second token and validates that both are valid. The intermediate gateway smart contract may then issue a temporary third token that represents a combination of the first set of transaction policies and the second set of transaction policies. In an embodiment, there may be any number of sets of transaction policies and an intermediate process may combine those sets of transaction policies in any number of ways. In an embodiment, the intermediate process may be carried out by gateway smart contract 3516.

FIG. 39 depicts tier structure 3900 of a hierarchical token, according to some embodiments.

In an embodiment, the transaction policies may depend on variable inputs. For example, the transaction policies may be more stringent for ecosystem transactions of higher values. A token may represent a hierarchy of the transaction policies that may start with less stringent transaction policies and may grow in stringency.

A token may represent all transaction policies up to a level in the hierarchy. As shown in FIG. 39 , various levels of hierarchies may be represented for transaction policies and their corresponding tokens. Bronze transaction policies 3902 may correspond to bronze token 3904, silver transaction policies 3906 may correspond to silver token 3908, and gold transaction policies 3910 may correspond to gold token 3912. Bronze token 3904 may represent all transaction policies of ecosystem transactions associated only with bronze transaction policies 3902. Silver token 3908 may represent all transaction policies of ecosystem transactions associated with both bronze transaction policies 3902 and silver transaction policies 3906 and may be presented as evidence to execute these ecosystem transactions. However, silver token 3908 may not allow ecosystem transactions associated with gold transaction policies 3910 to execute as credentials that correspond to gold transaction policies 3910 may not have been validated by trusted organization 3504. Further, gold token 3912 may represent all transaction policies of ecosystem transactions associated with bronze transaction policies 3902, silver transaction policies 3906, and gold transaction policies 3910 and may be presented as evidence to execute these ecosystem transactions.

In an embodiment, a trusted organization may only have authority to issue a token up to a level of the hierarchy (for example, up to an including “silver” level) and a more trusted organization may be required to issue a token for a higher level of the hierarchy.

FIGS. 40A and 40B depict a network of trusted organizations, according to some embodiments.

Trusted organizations may have a hierarchical structure which may allow one trusted organization to make changes to tokens issued by another trusted organization. In an embodiment, a trusted organization must be higher in the hierarchy to make changes to tokens issued by another trusted organization. In another embodiment, any trusted organization which is part of a network of trusted organizations may make changes to token issued by any other trusted organization in the network of trusted organizations.

FIG. 40A depicts hierarchical structure 4002 of a network of trusted organizations. Hierarchical structure 4002 of the network of trusted organizations may include first hierarchy 4004 of trusted organizations, second hierarchy 4006 of trusted organizations, and third hierarchy 4008 of trusted organizations. Trusted organization in first hierarchy 4004 may make changes to tokens issued by trusted organizations in all three hierarchies, i.e., first hierarchy 4004, second hierarchy 4006, and third hierarchy 4008. Trusted organizations in second hierarchy 4006 may make changes to tokens issued by trusted organizations only in second hierarchy 4006 and third hierarchy 4008. Trusted organizations in third hierarchy 4008 may make changes to tokens issued by trusted organizations only in third hierarchy 4008.

FIG. 40B depicts flat hierarchy structure 4010 of a network of trusted organizations. Flat hierarchy structure 4010 of the network of trusted organizations may include only single hierarchy 4012 of trusted organizations 3504. A trusted organization in single hierarchy 4012 may make changes to tokens issued by any other trusted organization in single hierarchy 4012.

According to aspects of the present disclosure, any trusted organization 3504 may have a public-private key pair which allows that trusted organization 3504 to issue and make changes to tokens. A public key of trusted organization 3504 is associated with a token issued by that trusted organization 3504. In an embodiment, gateway smart contract 3516 may dedicatedly manage all the tokens, and access to change details stored by gateway smart contract 3516 may be limited only to trusted organization(s) 3504 which hold the correct public key.

Gateway smart contract 3516 may store a database of public keys that have authority to make changes, and it may also store a hierarchy associated with each public key. In an example, a transaction to make a change to an issued token may be signed by the private key of trusted organization 3504, and the associated public key is searched in the database of public keys within gateway smart contract 3516. If the public key is found in the database of public keys and is allowed to make the change, gateway smart contract 3516 may execute the change to the issued token, otherwise the transaction is blocked.

In an embodiment, if a second trusted organization makes a change to a token issued by a first trusted organization, ownership of the token may be changed to the second trusted organization. In another embodiment, the ownership may be left unchanged.

In an embodiment, a single public-private key pair may be generated and all trusted organizations in a network of trusted organizations may share the same public-private key pair.

In an embodiment, data associated with issuance of tokens may be required by multiple centralized or distributed ledgers. According to aspects of the present disclosure, the tokens may be maintained (or stored) on the multiple centralized or distributed digital ledgers. In an embodiment, when trusted organization 3504 issues a token, trusted organization 3504 may execute the process once for each of the multiple centralized or distributed ledgers. Further, if trusted organization 3504 is required to process the token (for example, to change the state of the token), operations associated with the processing of the token are executed once for each of the multiple centralized or distributed ledgers.

In an embodiment, gateway smart contract 3516 which executes on a first centralized or distributed ledger may publish a record of tokens held on the first centralized or distributed ledger to each of the multiple centralized or distributed digital ledgers. The publication may occur each time a token is issued or a state of token (e.g. a state such as valid, expired, frozen, or revoked of a token) changes.

In an embodiment, a record of tokens may be held and maintained exclusively on a first centralized or distributed ledger and gateway smart contract 3516, which executes on a second centralized or distributed ledger may make a request to the first centralized or distributed ledger to determine presence and status of a token. The first centralized or distributed ledger may respond with a transaction on the second centralized or distributed ledger to report the requested presence and status of the token.

In an embodiment, a platform that manages ecosystem transactions using centralized or distributed ledger 3508 may detect, at the time of initiation of an ecosystem transaction, that user 3502 does not hold a valid token for the ecosystem transaction and may redirect user 3502 to trusted organization 3504. Once validation of credentials of user 3502 is carried out, user 3502 may be redirected back to the platform managing the ecosystem transactions.

FIG. 41 depicts flowchart 4100 for policy-validating transactions using a centralized or distributed ledger, according to some embodiments. In a brief overview of an implementation of flowchart 4100, at step 4102, a request may be received to execute an ecosystem transaction and a transaction signature generated with a private key of a computing device associated with user 3502.

In some implementations, step 4102 includes receiving a request to execute an ecosystem transaction and a transaction signature generated with a private key of a computing device associated with user 3502. According to an implementation, a first computing device in communication with centralized or distributed ledger 3508 may receive the request and the transaction signature from the computing device associated with user 3502. The ecosystem transaction may correspond to a token associated with the computing device of user 3502, and the ecosystem transaction may be subject to a first transaction policy of a set of one or more transaction policies. In an embodiment, the transaction may be identified as subject to the first transaction policy of the set of one or more transaction policies in response to one or more of the transaction, the token, and characteristics of the first computing device.

In some implementations, at step 4104, a public key of the computing device associated with user 3502 may be retrieved from a database and/or received from the computing device of the user (e.g. along with the request at step 4102, in some implementations).

In some implementations, at step 4106, the transaction signature may be verified with the public key (e.g. by decrypting the signature and matching the result to the transaction request, or other similar methods). In some implementations, step 4106 includes determining that the transaction signature corresponds to the request to execute the ecosystem transaction. In an implementation, the first computing device uses a public key of the computing device associated with user 3502 to determine that the transaction signature corresponds to the request to execute the ecosystem transaction.

If the signature is not verified, then at step 4108, the method may abort and/or may report an error (e.g. to the computing device of the user, to an administrator, to another computing device or server, by sending a signal to trigger an alarm, etc.). If the signature is verified, then in some implementations, at step 4110, the token associated with the computing device of the user may be retrieved from the centralized or distributed ledger 3508. In some implementations, step 4110 includes retrieving the token associated with the computing device of user 3502 in response to the determination that the signature is verified. According to an implementation, the first computing device may retrieve the token from centralized or distributed ledger 3508.

In an embodiment, the token may identify the first transaction policy and the token may comprise a status identifier. In an embodiment, the token may comprise an identifier indicating a validity period of the token.

In an embodiment, the set of one or more transaction polices may comprise a plurality of transaction policies in a parent-child hierarchy. The first transaction policy may be a child of a second transaction policy and the token may be further associated with the second transaction policy.

The token may be generated by a computing device and stored in centralized or distributed ledger 3508. The computing device generating the token may comprise a device of a user, a device of a third-party identity verifier, a device maintaining the centralized or distributed ledger, or any other such device. For example, in some embodiments, the transacting computing device (e.g. the computing device receiving a request to execute the ecosystem transaction and executing the transaction in response to determining that an associated token and/or policy are valid) may or may not be the computing device that issued the associated token and/or recorded the token on a centralized or distributed ledger. Accordingly, in various implementations, different steps of the methods discussed herein may be performed by the same device or different devices providing distributed operations. In an embodiment, the token may be stored in centralized or distributed ledger 3508 in response to validated credentials of user 3502 complying with the first transaction policy. In an embodiment, the token may be stored in centralized or distributed ledger 3508 in response to validation of a cryptographic nonce using the public and private key of the computing device of user 3502.

The token may be generated by one of the first computing device and a second computing device and stored in centralized or distributed ledger 3508. In an embodiment, the token may be stored in centralized or distributed ledger 3508 in response to validated credentials of user 3502 complying with the first transaction policy. In an embodiment, the token may be stored in centralized or distributed ledger 3508 in response to validation of a cryptographic nonce using the public and private key of the computing device of user 3502.

In some implementations, the token may be verified for validity (e.g. by determining that the token has not expired, according to an expiration time of the token recorded in the ledger; by determining that the token has a cryptographic signature corresponding to a public key of a token generator or validator; by determining that a transaction invalidating the token has not been recorded to the ledger; and/or by any other similar methods). If the token is not valid, then the method may abort and/or return errors at step 4108 as discussed above. If the token is valid, in some implementations, at step 4112, a policy associated with the transaction may be identified. For example, in some implementations, a database associating transactions and corresponding policies may be accessed and policies associated with the transaction of the request may be retrieved. In other implementations, one or more policies which are satisfied by the credentials associated with the token may be recorded to the ledger along with or as part of the token, and may be identified at step 4112 to determine if the one or more policies includes a policy associated with the transaction of the transaction request.

In some implementations, step 4112 includes determining that the token is associated with the first transaction policy and that the token is valid. In an implementation, the first computing device may determine that the token is associated with the first transaction policy and that the token is valid.

If the token is associated with the policy (or if the credentials used to generate or validate the token comply with the requirements or conditions of the policy), and the token is valid, then at step 4114, responsive to the determinations, the transaction may be executed. Step 4114 includes executing the transaction by the first computing device in response to the determination that the token is associated with the first transaction policy and that the token is valid. In an embodiment, to execute the transaction, the first computing device may direct a second computing device to provide access to a good or service to user 3502.

Accordingly, systems and methods are provided for policy-validated transactions using a centralized or distributed ledger. In an example embodiment, a method for policy-validated transactions using a centralized or distributed ledger is described, which includes receiving, by a first computing device in communication with a centralized or distributed ledger from a computing device associated with a user, a request to execute a transaction and a transaction signature generated with a private key of the computing device associated with the user, the transaction corresponding to a token associated with the computing device of the user, and the transaction subject to a first policy of a set of one or more policies; determining, by the first computing device using a public key of the computing device associated with the user, that the transaction signature corresponds to the request to execute the transaction; responsive to the determination, retrieving, by the first computing device from the centralized or distributed ledger, the token associated with the computing device of the user; determining, by the first computing device, that the token is associated with the first policy and that the token is valid; and responsive to the determination, executing the transaction, by the first computing device.

In some embodiments, the token identifies the first policy. In some embodiments, the token comprises a status identifier. In some embodiments, the token comprises an identifier of a validity period.

In some embodiments, the token is generated by one of the first computing device and a second computing device and stored in the centralized or distributed ledger. In some embodiments, the token is generated by the one of the first computing device and the second computing device and stored in the centralized or distributed ledger responsive to validated credentials of the user complying with the first policy. In some embodiments, the token is generated by the one of the first computing device and the second computing device and stored in the centralized or distributed ledger responsive to validation of a cryptographic nonce using the public and private key of the computing device associated with the user.

In some embodiments, the set of one or more polices comprise a plurality of policies in a parent-child hierarchy; wherein the first policy is a child of a second policy; and wherein the token is further associated with the second policy.

In some implementations, the method further includes identifying the transaction as subject to the first policy of the set of one or more policies responsive to one or more of the transaction, the token, and characteristics of the first computing device.

In some implementations, executing the transaction further comprises directing a second computing device, by the first computing device, to provide access to a good or service to the user.

In another example implementation, a system for rules-validated transactions using a centralized or distributed ledger is described, which includes a first computing device comprising a network interface in communication with a computing device associated with a user and a memory device storing a centralized or distributed ledger, and a processor. The processor is configured to receive, via the network interface from the computing device associated with the user, a request to execute a transaction and a transaction signature generated with a private key of the computing device associated with the user, the transaction corresponding to a token associated with the computing device of the user, and the transaction subject to a first policy of a set of one or more policies, determine, using a public key of the computing device associated with the user, that the transaction signature corresponds to the request to execute the transaction, responsive to the determination, retrieve, from the centralized or distributed ledger, the token associated with the computing device of the user, determine that the token is associated with the first policy and that the token is valid, and responsive to the determination, execute the transaction.
